The packing densification of trilobes in rectangular containers of varying aspect ratios is systematically investigated using a geometrically exact contact detection algorithm combined with the multi-sphere method. Packing structures are analyzed in terms of overall density, spatial packing density distribution, radial distribution function, and densification mechanisms. Under mechanical vibration, two preferential particle orientations are identified. At low vibration amplitudes, spatial confinement in the bottom layer restricts rearrangement of trilobes, resulting in partial vertical alignment while many particles remain parallel to the container base. At higher amplitudes, increased mobility facilitates extensive reorientation and structural reconfiguration of trilobes, allowing nearly all trilobes near the bottom aligning vertically. In rectangular containers, trilobes predominantly adopt orientations either parallel or perpendicular to the container base, forming granular beds composed of ordered clusters of distinct orientations. The crystallization process is prohibited by the joint effects of the two distinct preferential orientations and the strong interlockings between trilobed particles and a random close packing of trilobed particles is formed in the containers. Notably, the overall packing density is not determined by the degree of crystallization but by the spatial arrangements of clusters of distinct orientations which is not sensitive to the geometry of the rectangular containers; granular beds consisting of ordered clusters with relatively low nematic order parameters can achieve higher global packing densities.

采用几何精确接触检测算法与多球法相结合的方法，系统地研究了不同宽高比矩形容器中三叶片的填充致密性。从总体密度、空间密度分布、径向分布函数和致密化机理等方面分析了填料结构。在机械振动下，确定了两种优先的粒子取向。在低振动幅值时，底层的空间限制限制了三叶瓣的重新排列，导致部分垂直排列，而许多颗粒保持与容器底部平行。在更高的振幅下，流动性的增加有助于三叶的广泛重新定向和结构重新配置，几乎所有靠近底部的三叶都可以垂直对齐。在矩形容器中，三叶叶主要采用与容器基部平行或垂直的方向，形成由不同方向的有序簇组成的颗粒床。两种不同的优先取向和三叶颗粒之间的强互锁的共同作用禁止了结晶过程，并在容器中形成了三叶颗粒的随机紧密堆积。值得注意的是，总体堆积密度不是由结晶程度决定的，而是由不同取向簇的空间排列决定的，这对矩形容器的几何形状不敏感；由有序簇组成的颗粒床具有相对较低的向列序参数，可以获得较高的整体堆积密度。

The development of hybrid aluminum matrix composites (HAMCs) reinforced with superhard carbides is a crucial scientific direction, which still faces challenges related to the inhomogeneous distribution of reinforcing component and the formation of undesirable interphase compounds. This study was aimed to develop a universal in-situ approach for plasma dynamic synthesis of HAMCs with enhanced structural, mechanical, and functional properties. Dispersed powders of HAMCs reinforced with WC, SiC, and B₄C were produced by high-speed spraying of a multicomponent thermal plasma jet, followed by spark plasma sintering (SPS) to fabricate bulk materials. The developed plasma processing technology provides complete alignment of the HAMCs components and form a composite structure with a polymodal particle size distribution, where the aluminum matrix is primarily presented with porous microsized particles filled in by ceramic component. These features of composite powders affect high mechanical properties of bulk sintered samples with density values of up to 99 % and microhardness values of up to 134 HV, which exceed those of known analogs and pure aluminum. A combination of high mechanical, thermal and electrical properties confirms the functionality of synthesized materials and highlights the potential of applying in-situ approach based on plasma processes for producing advanced HAMCs with improved performance characteristics.

超硬碳化物增强杂化铝基复合材料（HAMCs）的研究是一个重要的科学方向，但仍面临着增强组分分布不均匀和不良相化合物形成的挑战。本研究旨在开发一种通用的原位等离子体动态合成具有增强结构、力学和功能特性的hamc的方法。采用多组分热等离子体射流高速喷涂制备WC、SiC和B4C增强hamc分散粉末，然后采用火花等离子体烧结（SPS）制备块状材料。所开发的等离子体处理技术使hamc组件完全对齐，形成具有多模态粒度分布的复合结构，其中铝基体主要呈现由陶瓷组件填充的多孔微颗粒。复合粉末的这些特性影响了大块烧结样品的高力学性能，其密度值高达99%，显微硬度值高达134 HV，超过了已知的类似物和纯铝。高机械、热学和电学性能的结合证实了合成材料的功能，并强调了应用基于等离子体工艺的原位方法生产具有改进性能特征的先进hamc的潜力。

Given the growing emphasis on sustainable industrial practices and regulatory constraints on particulate emissions, enhancing cyclone separator performance remains a critical area of research for ensuring the high-efficient solid-gas separation with minimal energy penalties. This study presents a comprehensive numerical investigation and multi-objective optimisation of a dual-inlet cyclone separator to enhance the particle collection efficiency while minimizing the pressure drop. The Eulerian-Lagrangian approach is employed using the RNG

turbulence modelling, coupled with the Discrete Phase Model for particle tracking. Key geometric parameters, including the inlet height to width, vortex finder angle, vortex finder diameter, barrel height, cone height, and bin diameter, are systematically varied to analyse their effects on the cyclone performance. Two optimal factors are tested among the three most significant factors at once to evaluate their combined effects on the collection efficiency and the pressure drop. Results indicate that the optimised cyclone design improves average collection efficiency by 11.5 % across particle sizes, reduces the Euler number by 50.96 %, and lowers the particle cut-off diameter by 16.15 %, while maintaining a balanced trade-off with the pressure drop. The prediction errors for the pressure drop and the collection efficiency are within acceptable limits at 11 % and 3.5 %, respectively. The improved geometry strengthens the tangential flow and moderates the peak axial velocity, resulting in a more effective centrifugal separation for fine particles.

鉴于对可持续工业实践的日益重视和对颗粒排放的监管限制，提高旋风分离器的性能仍然是确保以最小的能源损失实现高效固气分离的关键研究领域。本文对双入口旋风分离器进行了全面的数值研究和多目标优化，以提高颗粒收集效率，同时最小化压降。欧拉-拉格朗日方法采用RNG k-ε湍流模型，并结合离散相位模型进行粒子跟踪。系统地改变了主要几何参数，包括入口高度与宽度、涡流探测仪角度、涡流探测仪直径、桶高、锥高和料仓直径，以分析它们对旋风分离器性能的影响。在三个最重要的因素中同时测试两个最优因素，以评估它们对收集效率和压降的综合影响。结果表明，优化后的旋风分离器设计使不同粒径的平均收集效率提高了11.5%，欧拉数降低了50.96%，颗粒截止直径降低了16.15%，同时保持了与压降的平衡权衡。对压降和收集效率的预测误差分别为11%和3.5%，均在可接受范围内。改进的几何形状加强了切向流动，缓和了轴向速度峰值，从而更有效地对细颗粒进行离心分离。

The performance of photovoltaic cell grids critically depends on the quality of front silver paste, which is significantly influenced by the particle size of the silver powder. Liquid-route continuous synthesis is a highly promising option for the silver micro-powder production. To identify the key factors in synthesis processes impacting on the particle size of the final product, a comprehensive understanding of the continuous liquid-route reduction synthesis mechanisms is required. This study presents a coupled CFD-PBM framework of silver micro-powder synthesis that incorporates flow dynamics, chemical reactions, nucleation, and surface growth processes. The results indicate that the initial reduction rate influences the nucleation of silver powder formation, thereby determining the number of final products. The reduction rate of following stage affects the surface growth, ultimately determining the average size of the products. In a synthesis system with a fixed total reducible silver content, a high initial reduction rate tends to a larger number of smaller silver powder particles produced. Particularly in the ascorbic acid-silver nitrate reduction system, the pH value is a critical factor controlling the distribution of reaction rates. The findings reveal how the reduction rate regulates the final particle size through its influence on nucleation and growth processes, providing insights into controlling powder particle size characteristics by manipulating reaction rates within the continuous synthesis system.

光伏电池栅极的性能关键取决于前端银浆的质量，而前端银浆的质量又受银粉粒度的显著影响。液路连续合成是一种极有前途的银微粉生产方法。为了确定合成过程中影响最终产品粒度的关键因素，需要全面了解连续液路还原合成机制。本研究提出了一种结合流动动力学、化学反应、成核和表面生长过程的耦合CFD-PBM银微粉合成框架。结果表明，初始还原速率影响银粉的成核，从而决定最终产物的数量。后续阶段的还原速率影响表面生长，最终决定产品的平均尺寸。在总可还原银含量固定的合成体系中，初始还原率越高，产生的银粉颗粒越小。特别是在抗坏血酸-硝酸银还原体系中，pH值是控制反应速率分布的关键因素。研究结果揭示了还原速率如何通过其对成核和生长过程的影响来调节最终粒度，为通过操纵连续合成系统中的反应速率来控制粉末粒度特征提供了见解。

Clay-type lithium ores represent a vast, underexploited resource critical for future lithium supply, but their complex mineralogy hinders efficient processing. While alkaline pretreatment is a promising enrichment strategy, its optimization is hampered by elusive regulatory mechanisms. Here, we report a critical non-monotonic response where excessive pretreatment intensity paradoxically suppresses lithium recovery. We identify and verify that this response is governed by a key antagonistic mechanism, termed the Alkali Residue Effect (ARE), where residual alkaline species cause both physical dilution and chemical neutralization. Through response surface methodology (RSM) targeting the mitigation of ARE, we established an optimized processing window that achieves a 4.35-fold lithium enrichment (Li₂O from 0.17 to 0.74 wt%). Microscopic analyses (SEM-EDS, XRD, XPS) confirm the optimized process selectively etches amorphous gangue, enhancing the reactivity of the Li-bearing mineral (cookeite). A techno-economic analysis projects a favorable operating cost of ∼US$81/ton. This study provides a new theoretical framework (ARE) for optimizing complex hydrometallurgical processes by balancing targeted reactions against unintended side effects.

粘土型锂矿石是一种巨大的未开发的资源，对未来的锂供应至关重要，但其复杂的矿物结构阻碍了有效的加工。虽然碱性预处理是一种很有前途的富集策略，但其优化受到难以捉摸的调控机制的阻碍。在这里，我们报告了一个关键的非单调响应，其中过度的预处理强度矛盾地抑制了锂的回收。我们确定并验证了这种反应是由一种关键的拮抗机制控制的，称为碱残留效应（ARE），其中残留的碱性物质导致物理稀释和化学中和。通过针对ARE的响应面法（RSM），我们建立了一个优化的处理窗口，实现了4.35倍的锂富集（Li2O从0.17 wt%增加到0.74 wt%）。微观分析（SEM-EDS， XRD， XPS）证实，优化后的工艺选择性地蚀刻无定形脉石，提高了含锂矿物（cookeite）的反应性。一项技术经济分析预测，有利的运营成本为每吨81美元。该研究为通过平衡目标反应和意外副作用来优化复杂的湿法冶金过程提供了一个新的理论框架。

Material extrusion is a key step in the solvent-free fabrication of lithium-ion battery (LIB) electrodes, offering reduced costs and environmental impact compared to slurry-based methods. While discrete element method (DEM) based mesoscopic models have been used to study twin-screw extrusion, the microstructural characterisation of extrudates immediately after nozzle exit remains unexplored. In this study, a series of DEM simulations were conducted to perform a sensitivity analysis of the microstructure and electrochemical performance-related parameters of extruded electrode filaments by varying the feeding rate and feeding mode, screw rotational speed, and particle cohesion. Furthermore, this work addresses the previously unexamined phenomenon of filament expansion during extrusion. By introducing the Augmented Dickey-Fuller (ADF) method, the study also provides the first analysis of the temporal dynamic stability of filament quality during the dry electrode manufacturing extrusion process. The results show that increasing the screw speed from 100 to 500 RPM reduces porosity by 10 % and limits expansion, while lower speeds improve consistency in electrode quality. A novel approach to quantifying dynamic behaviour is proposed, offering insights for optimising solvent-free electrode manufacturing.

材料挤压是无溶剂制造锂离子电池（LIB）电极的关键步骤，与基于浆料的方法相比，可以降低成本和对环境的影响。虽然基于离散元方法（DEM）的细观模型已被用于研究双螺杆挤压，但挤出物在喷嘴出口后的微观结构特征仍未被探索。在本研究中，通过一系列DEM模拟，通过改变进料速率和进料方式、螺杆转速和颗粒内聚力，对挤压电极细丝的微观结构和电化学性能相关参数进行敏感性分析。此外，这项工作解决了以前未检查的现象，长丝膨胀期间挤压。通过引入ADF （Augmented Dickey-Fuller）方法，首次分析了干电极制造挤压过程中长丝质量的时间动态稳定性。结果表明，将螺杆转速从100转/分提高到500转/分，气孔率降低了10%，并限制了膨胀，而较低的转速提高了电极质量的一致性。提出了一种量化动态行为的新方法，为优化无溶剂电极制造提供了见解。

Erosion of water-cooled walls is a major challenge affecting the reliability and efficiency of circulating fluidized bed (CFB) boilers. To mitigate this issue, this study employs computational particle fluid dynamics (CPFD) simulations to optimize the design of a novel honeycomb anti-wear structure. The results show that honeycomb installation slightly modifies local wall flow but has negligible influence on the overall pressure drop. When positioned in the dense phase region, the honeycomb effectively reduces wall erosion to less than 10 % of its original value at most locations through shielding against particle impingement. Increasing the installation height weakens this effect due to stronger lateral particle motion. Thicker honeycombs enhance protection, with 7 cm achieving optimal performance, while 5 cm is sufficient in the dense phase region. The findings demonstrate that an appropriately designed honeycomb structure can serve as an innovative and effective method to mitigate erosion and extend wall service life. The synergistic combination of this structural design with metallic–ceramic coatings presents a promising strategy for enhancing both durability and heat transfer efficiency in industrial CFB boilers.

水冷壁侵蚀是影响循环流化床锅炉可靠性和效率的主要问题。为了缓解这一问题，本研究采用计算颗粒流体动力学（CPFD）模拟来优化新型蜂窝抗磨结构的设计。结果表明，蜂窝装置对局部壁面流动的影响较小，但对整体压降的影响可以忽略不计。当蜂窝位于致密相区时，通过屏蔽颗粒撞击，在大多数位置有效地将壁面侵蚀降低到原始值的10%以下。增加安装高度会减弱这种效应，因为横向粒子运动更强。较厚的蜂窝增强了保护作用，7厘米达到最佳性能，而在密相区域5厘米就足够了。研究结果表明，适当设计蜂窝结构可以作为一种创新和有效的方法来减轻侵蚀和延长墙体的使用寿命。这种结构设计与金属陶瓷涂层的协同结合为提高工业循环流化床锅炉的耐用性和传热效率提供了一种有前途的策略。

Gas-solid two-phase flows are common in both industrial processes and natural phenomena, and accurately detecting particle properties within these flows is crucial for process optimization and control. However, existing particle detection techniques often struggle to provide in-situ, real-time, and multi-parameter measurements in complex flow environments. To address this challenge, a new digital holographic probe, designed for compactness and 3D measurement capability, is developed in this work. The delicate structure of the probe head makes it suitable for use in pneumatically conveyed particle flows within pipes, with a measurement volume of 435.6 mm³. The measurement performance of the holographic probe has been verified on a pipeline pneumatic transport test platform under various particle size and concentration conditions. Using 3D holographic imaging, the spatial distribution of particles within the measurement volume was analyzed. Experimental results show that the relative deviation of the mass median diameter is less than 3 %, while the relative deviation of the average mass concentration is below 12 %, compared to reference results.

This study designs and analyzes two high-performance hybrid micromixers: a multi-channel type Mixer 1 and a super-efficient type Mixer 2. Mixer 1 integrates a tree-shape distributor with Split-and-Recombine (SAR) mixers, while Mixer 2 incorporates an additional tree-shape Focus mixer after the SAR mixers. Mixing performance was analyzed across a Reynolds number (Re) range of 0.5–120. The distributor, designed via entropy generation minimization, uniformly splits flow into eight outlets while preserving the inlet concentration distribution. The SAR unit significantly enhances transverse mass transport through Baker's transformation and secondary flows. Using over four SAR units yields >90 % efficiency across the entire Re range. The Focus mixer reduces fluid-layer thickness through bifurcation-merging processes and induces secondary flow; with four branching generations, its efficiency surpasses 90 % at Re > 10 and 99 % at Re > 35. In hybrid configurations with six SAR units, Mixer 1 exhibits a mixing efficiency dip to 95 % for Re = 6 across all outlets, exceeding 99 % for Re < 3 and Re > 8. Mixer 2 also shows a dip at Re = 6, but its minimum efficiency remains >97 %, validating its ultra-high-efficiency design.

本研究设计并分析了两种高性能混合微混频器：多通道混合器1和超高效混合器2。混合器1集成了一个树形分布与分裂和重组（SAR）混合器，而混合器2合并了一个额外的树形焦点混合器后的SAR混合器。在0.5 ~ 120雷诺数范围内对混合性能进行了分析。通过最小化熵生成设计的分配器，在保持入口浓度分布的同时，均匀地将水流分成八个出口。SAR单元通过贝克变换和二次流显著增强了横向质量输运。使用四个以上的SAR单元，在整个Re范围内的效率为90%。Focus混合器通过分岔合并过程减小流层厚度，诱导二次流；在四个分支世代中，其效率在Re >； 10和Re >； 35时分别超过90%和99%。在具有六个SAR单元的混合配置中，混合器1在所有出口的Re = 6的混合效率降至95%，而在Re <； 3和Re >； 8的混合效率超过99%。混合器2在Re = 6时也显示出下降，但其最低效率保持在97%，验证了其超高效率设计。

Debris flows, a common natural disaster, cause annual casualties and property damage downstream. In mountainous watersheds, short-duration heavy rainfall generates significant hydraulic conditions in debris flow channels. The specified conditions trigger the mobilization of loose sediment, leading to the amplification effect that can ultimately overwhelm downstream mitigation measures. This study considers the influence of the fluid properties of viscous debris flow slurries on the forces exerted on buried coarse particles, aiming to accurately reflect real-world conditions and offer theoretical support for the amplification effect. A novel relationship was established between the initiation of motion for buried coarse particles and flow conditions, thereby broadening the applicability of existing models. The reliability of the model is assessed from two perspectives: comparison with physical model experiments and comparison with numerical simulations. A sensitivity analysis on the fluid property parameters of the debris flow slurry revealed that slurry density has the greatest impact on the cross-sectional initiation velocity for particle initiation, followed by fluid yield stress, fluid consistency index, and fluid behavior index, with the latter having the least influence.

泥石流是一种常见的自然灾害，每年都会给下游地区造成人员伤亡和财产损失。在山地流域，短时强降雨对泥石流通道产生重要的水力条件。特定条件触发松散沉积物的动员，导致放大效应，最终可能压倒下游的缓解措施。本研究考虑粘性泥石流浆体的流体性质对埋地粗颗粒受力的影响，旨在准确反映真实情况，为放大效应提供理论支持。建立了埋地粗颗粒起始运动与流动条件之间的新关系，从而拓宽了现有模型的适用性。从与物理模型实验的比较和与数值模拟的比较两方面对模型的可靠性进行了评价。对泥石流浆体流体性质参数的敏感性分析表明，浆体密度对颗粒起爆截面起裂速度的影响最大，其次是流体屈服应力、流体稠度指标和流体行为指标，后者的影响最小。
