In vertical hydraulic conveyance for deep-sea mining, localized particle aggregation can occur due to multiple factors, resulting in increased concentration and degrade transport performance. To mitigate this issue, this study proposes a novel deflector vane-type swirl generator with a simple structure that generates swirling flow without additional operations. A combined computational fluid dynamics (CFD) and discrete element method (DEM) has been used to numerically simulate liquid-solid swirling flow in a vertical pipe featuring the vane. Subsequently, an orthogonal design method was applied to evaluate the effects of vane number, vane angle, vane radius, and hub diameter on transport behavior, using the horizontal dispersion coefficient and pressure drop as performance indicators. The results demonstrate that the vane angle is the most influential factor for both particle dispersion and pressure loss, whereas vane number and vane radius have comparatively minor effects. Moreover, increasing the vane angle and hub diameter strengthens the swirl intensity, promotes particle accumulation near the pipe wall, and thereby increases the horizontal dispersion coefficient. The results offer insights that can inform the enhancement of the efficiency and safety of vertical hydraulic transport.

在深海采矿垂直水力输送中，多种因素会导致颗粒局部聚集，导致颗粒浓度升高，降低输送性能。为了缓解这一问题，本研究提出了一种结构简单的新型偏转叶片型旋流发生器，无需额外操作即可产生旋流。采用计算流体力学（CFD）和离散元法（DEM）相结合的方法，对具有叶片的垂直管道中的液固旋流进行了数值模拟。随后，采用正交设计方法，以水平分散系数和压降为性能指标，评估叶片数量、叶片角度、叶片半径和轮毂直径对输送行为的影响。结果表明，叶片角度对颗粒分散和压力损失的影响最大，叶片数和叶片半径的影响相对较小。增大叶片角度和轮毂直径可增强旋流强度，促进颗粒在管壁附近积聚，从而提高水平弥散系数。研究结果为提高垂直水力输送的效率和安全性提供了参考。

The utilization of granite powder (GP) is substantially limited by its low pozzolanic activity and inert structure, posing a significant challenge for its high-volume incorporation. This study conducts experimental research on cold-bonded ceramsite based on the GP–fly ash–cement system, adopting the modified Andreasen–Andersen (MAA) particle packing model as a tool for mix ratio design and evaluation. By designing multiple groups of different particle size combinations, the raw material particle gradation is made to produce controllable deviations from the MAA target curve within a certain range. RSS is used to quantitatively characterize the degree of deviation of the particle gradation from the MAA target curve, and the influence mechanism of this deviation on the physical properties and pore structure of ceramsite is systematically analyzed. The results indicated that an RSS value of 6736 yielded the most compact ceramsite structure, which exhibited a cylinder compressive strength of 5.76 MPa, a bulk density of 1041 kg/m³, and a water absorption as low as 12.65 %. Further particle size fractionation experiments revealed that single-size raw material systems performed significantly worse than full-range particle distributions. The latter facilitated the formation of a skeleton–filler collaborative structure, thereby enhancing compactness and mechanical stability. Compared with existing utilization pathways of GP, the proposed structure-regulated preparation strategy for cold-bonded ceramsite enables up to 85 % incorporation of GP and delivers comprehensive performance improvement without reliance on high-temperature sintering or alkali activation. This approach demonstrates considerable engineering feasibility and application potential, providing a novel perspective and theoretical foundation for the high-efficiency valorization of low-activity solid wastes.

花岗岩粉（GP）的利用受到其低火山灰活性和惰性结构的极大限制，对其大量掺入提出了重大挑战。本研究采用改进的MAA （Andreasen-Andersen）颗粒充填模型作为配合比设计与评价工具，对gp -粉煤灰-水泥体系的冷粘陶粒进行了试验研究。通过设计多组不同粒度的组合，使原料粒度级配在一定范围内与MAA目标曲线产生可控偏差。采用RSS定量表征了颗粒级配与MAA目标曲线的偏离程度，系统分析了这种偏离对陶粒物理性质和孔隙结构的影响机理。结果表明，当相对过饱和度为6736时，陶粒结构最致密，筒体抗压强度为5.76 MPa，容重为1041 kg/m3，吸水率低至12.65%。进一步的粒度分馏实验表明，单一粒度的原料系统的性能明显差于全范围的颗粒分布。后者促进了骨架-填料协同结构的形成，从而提高了密实度和机械稳定性。与现有的GP利用途径相比，本文提出的结构调节冷粘合陶粒制备策略使GP的加入率高达85%，并且在不依赖高温烧结或碱活化的情况下实现了全面的性能改善。该方法具有相当的工程可行性和应用潜力，为低活性固体废物的高效增值提供了新的视角和理论基础。

To ensure the health and safety of astronauts during future manned lunar missions, it is critical to understand the transport and deposition of lunar dust (LD) particles in the terminal alveoli. This study employs computational fluid dynamics (CFD) to investigate the deposition characteristics of LD particles, considering factors such as particle size, activity intensity, and body posture. The key findings are: (1) The deposition characteristics of LD particles differ significantly across various activity intensities, with higher activity levels resulting in earlier onset and shorter duration of deposition. (2) The distributions and rates of deposited particles on the alveolar wall vary with different body postures. Specifically, transitioning from a head-up to a head-down posture leads to a reduction of 4.51 times in deposition time. (3) A predictive equation has been developed that effectively estimates LD particle deposition in the terminal alveoli by accounting for particle size, activity level, and body posture. In conclusion, LD particles display diverse deposition characteristics in the terminal alveoli, which can be accurately predicted using an appropriate fitting equation. The findings of this study may significantly enhance astronaut safety and well-being during future manned space exploration missions.

为了确保未来载人登月任务中宇航员的健康和安全，了解月尘颗粒在终端肺泡中的运输和沉积是至关重要的。本研究采用计算流体力学（CFD）研究LD颗粒的沉积特征，考虑颗粒大小、活动强度和身体姿势等因素。结果表明：(1)不同活性强度下LD颗粒的沉积特征存在显著差异，活性水平越高，沉积开始时间越早，沉积持续时间越短；(2)肺泡壁上沉积颗粒的分布和速率随体位的不同而不同。具体来说，从平头姿势转变为平头向下姿势，沉积时间减少了4.51倍。(3)建立了一个预测方程，通过考虑颗粒大小、活动水平和身体姿势，有效地估计LD颗粒在终末肺泡中的沉积。综上所述，LD颗粒在终末肺泡中表现出不同的沉积特征，可以通过合适的拟合方程准确预测。本研究结果可能会显著提高未来载人航天探索任务中宇航员的安全和福祉。

During the flue gas desulfurization process with the circulating fluidized bed (CFB) reactor, Geldart C desulfurization ash particles are prone to aggregation and accumulation in the inlet region, which significantly impairs gas-solid contact. To address this challenge, the present study proposes a novel design that couples a loop reactor to the bottom of the riser and employs a tangential intake structure. This combination generates a swirling flow to enhance the fluidization performance of Geldart C particles in the inlet region of the CFB reactor, thereby improving gas-solids contact efficiency. Under a superficial gas velocity of 1.5–4.5 m/s, the tangential intake configuration facilitates the formation of draft tube-lift loop flow when the draft tube gas velocity exceeds 1.10 m/s. In comparison, the vertical intake requires a gas velocity in the draft tube region greater than 1.20 m/s, while the coiled intake demands 1.25 m/s. Furthermore, the swirling-flow from tangential intake effectively entrains more Geldart C particles into the internal loop flow and external circulation, increasing the solids circulation rate from 7.0 to 10.0 kg/(m² s), an increase of 42.9 %. These findings offer a valuable insight for the industrial application of Geldart C particles in CFB systems.

循环流化床（CFB）反应器烟气脱硫过程中，Geldart C脱硫灰颗粒容易在入口区聚集堆积，严重影响气固接触。为了解决这一挑战，本研究提出了一种新的设计，将环形反应器耦合到立管底部，并采用切向进气结构。这种组合产生旋流，增强了Geldart C颗粒在CFB反应器入口区的流态化性能，从而提高气固接触效率。在表层气速为1.5 ~ 4.5 m/s时，切向进气配置有利于尾水管气速超过1.10 m/s时尾水管-升力环流的形成。相比之下，垂直进气道要求尾水管区域的气流速度大于1.20 m/s，而盘管进气道要求1.25 m/s。此外，切向进气道的旋流有效地将更多的Geldart C颗粒带入内环流和外循环，使固体循环速率从7.0 kg/(m2 s)提高到10.0 kg/(m2 s)，提高了42.9%。这些发现为Geldart C粒子在CFB系统中的工业应用提供了有价值的见解。

This study presents a systematic methodology for producing multi-walled carbon nanotubes (MWCNTs)/Inconel 718 composite powder, especially for the Laser Directed Energy Deposition (LDED) process. This approach integrates mild oxidative functionalization of MWCNTs to reduce agglomerations and High-Energy Ball Milling (HEBM) to enhance dispersion over the Inconel 718 powder. The MWCNTs were functionalized through a two-step chemical treatment: (1) magnetic stirring in a 3:1 H₂SO₄ and HNO₃ solution, using two distinct acid concentrations (3 M and 8 M), followed by (2) an ultrasonic bath in H₂O₂ solution. Structural defects were characterized using Raman spectroscopy (RS), thermogravimetric analysis (TGA), and transmission electron microscopy (TEM), while X-ray photoelectron spectroscopy (XPS) quantified the amount of oxygen-containing functional groups. Among the six functionalization processes, the treatment condition involving 4 h of magnetic stirring, then 2 h in the sonication bath, emerged as optimal, yielding a relatively high functional group attachment (11.47 %) with lower surface defects and without compromising uniformity in mixing. The FESEM analysis of the functionalized MWCNTs (up to 2 wt%)/Inconel 718 composite powder, collected from the LDED machine bed, confirmed uniform dispersion, validating the functionalization strategy. Although developed for LDED, this strategy is also suitable for MMC production processes that use powder as feedstock.

本研究提出了一种制备多壁碳纳米管(MWCNTs)/Inconel 718复合粉末的系统方法，特别是激光定向能沉积（LDED）工艺。该方法结合了MWCNTs的轻度氧化功能化以减少团聚，以及高能球磨（HEBM）以增强Inconel 718粉末的分散。MWCNTs通过两步化学处理实现功能化：(1)在3:1的H2SO4和HNO3溶液中进行磁力搅拌，使用两种不同的酸浓度（3 M和8 M），然后(2)在H2O2溶液中进行超声波浴。利用拉曼光谱（RS）、热重分析（TGA）和透射电子显微镜（TEM）对结构缺陷进行了表征，x射线光电子能谱（XPS）对含氧官能团的数量进行了量化。在6种功能化工艺中，先进行4小时磁力搅拌，然后在超声浴中进行2小时的处理条件是最佳的，可以产生相对较高的官能团附着（11.47%），表面缺陷较低，且不影响混合的均匀性。从led机床上收集的功能化MWCNTs（高达2 wt%）/Inconel 718复合粉末的FESEM分析证实了均匀分散，验证了功能化策略。虽然是为led开发的，但该策略也适用于使用粉末作为原料的MMC生产过程。

Oxygen evolution reaction (OER) plays a vital role in various pivotal electrochemical applications. To improve the energy efficiency and economic viability of these technologies, it is critical to develop cost-effective and highly active OER electrocatalysts based on earth-abundant elements. Among various candidates, transition-metal-based compounds have demonstrated notable potential for OER electrocatalysis, attributable to their adjustable electronic configurations. Nevertheless, their practical application remains constrained by limited intrinsic activity, poor electrical conductivity, and particle aggregation, which compromise their overall OER efficiency. In this study, an efficient OER electrocatalyst, S-NiFc MOF@Mo₂CT_x, is constructed by the sulfidation of NiFe-based metal–organic framework (MOF) precursors anchored on conductive Mo₂CT_x MXene. The MOF-derived NiFe sulfides offer abundant accessible active sites, and the strong interfacial coupling between NiFe sulfides and Mo₂CT_x enhances the catalyst's intrinsic activity. The conductive Mo₂CT_x matrix also guarantees efficient electron transport and homogeneous dispersion of the active phase. As a result, S-NiFc MOF@ Mo₂CT_x exhibits excellent OER activity, reaching 10 mA cm⁻² at an overpotential of 223 mV, along with stable operation for 68 h in 1.0 M KOH solution. This study broadens the scope of MXene-based materials in electrocatalytic applications and offers valuable insights into optimizing NiFe-derived OER catalysts.

析氧反应（OER）在各种关键电化学应用中起着至关重要的作用。为了提高这些技术的能源效率和经济可行性，开发具有成本效益和高活性的基于地球丰富元素的OER电催化剂至关重要。在各种候选化合物中，过渡金属基化合物由于其可调节的电子结构而表现出显著的OER电催化潜力。然而，它们的实际应用仍然受到固有活性有限、导电性差和粒子聚集的限制，这些都会影响它们的整体OER效率。在这项研究中，一种高效的OER电催化剂S-NiFc MOF@Mo2CTx是通过将nfe基金属有机框架（MOF）前驱体固定在导电的Mo2CTx MXene上进行硫化而构建的。mof衍生的NiFe硫化物提供了丰富的可达活性位点，并且NiFe硫化物与Mo2CTx之间的强界面耦合提高了催化剂的本征活性。导电Mo2CTx基体还保证了有效的电子传输和活性相的均匀分散。因此，S-NiFc MOF@ Mo2CTx表现出优异的OER活性，在223 mV过电位下达到10 mA cm−2，并在1.0 M KOH溶液中稳定运行68小时。这项研究拓宽了mxene基材料在电催化应用中的范围，并为优化nfe衍生的OER催化剂提供了有价值的见解。

Trickle bed reactors are frequently applied in the chemical process industries for gas-liquid-solid contacting. The performance of these reactors is sensitively influenced by the hydrodynamics. This study focuses on investigating the complex interaction between the gas and liquid phases in these reactors. Specifically, the effects of inlet liquid flux, surface wettability, and gas velocity on lateral spreading and axial penetration of the liquid are explored. An ordered trickle bed is used to reduce the effects of the configuration of the particles on these parameters. Using Direct Numerical Simulation (DNS), we determined that the lateral spreading and axial penetration are enhanced with an increased liquid flux, as expected. Interestingly, the initial liquid inertia, represented by the liquid jet velocity, has limited influence on both lateral spreading and axial penetration in the ordered bed, while the gravitational force is the dominant factor for the axial penetration. Furthermore, the contact angle has minimal impact on lateral spreading, indicating the presence of an additional force restricting spreading. Notably, the gas velocity is identified as a crucial factor influencing lateral spreading, as high velocities prevent the capillary forces from spreading the liquid. These insights in the contributing forces on the spreading behaviour in trickle bed reactors facilitate an improved reactor design and optimization.

滴流床反应器是化工过程中常用的气液固接触反应器。这些反应器的性能受流体力学的敏感影响。本研究的重点是研究这些反应器中气、液相之间复杂的相互作用。具体而言，研究了进口液体通量、表面润湿性和气体速度对液体横向扩散和轴向渗透的影响。采用有序滴流床来减少颗粒结构对这些参数的影响。使用直接数值模拟（DNS），我们确定横向扩散和轴向穿透随着液体通量的增加而增强，正如预期的那样。有趣的是，以射流速度为代表的初始液体惯量对有序层的横向扩展和轴向渗透的影响都有限，而重力是轴向渗透的主导因素。此外，接触角对横向扩散的影响最小，表明存在额外的力限制扩散。值得注意的是，气速被认为是影响横向扩散的关键因素，因为高速可以阻止毛细力扩散液体。这些对滴流床反应器扩散行为的贡献力的见解有助于改进反应器的设计和优化。

This article investigated the hydrodesulfurization of shale oil over NiMo/Al₂O₃ catalyst in a fixed bed reactor downstream a methanol steam reformer that provides H₂-rich gas containing CO₂ and steam. Under the optimal conditions of hydrogenation, say, at 380 °C, 4 MPa, a gas/oil volume ratio of 600:1, and an oil hourly space velocity of 4.0 h⁻¹, the sulfur content in the upgraded shale oil varied around 4400 ppm, showing a sulfur removal efficiency above 66 % and the satisfaction of the international standard for marine fuel oil (ISO 8217). The oil exhibited significant improvement on quality, including enhanced calorific value, reduced density and viscosity, increased fraction of light oil, and decreased proportion of heavy oil. Through characterization of catalysts, it was found that steam in H₂-rich gas did not significantly affect hydrodesulfurization efficiency. The presence of steam not only promoted hydrocracking of heavy fractions but reduced also carbon deposition on the catalyst during hydro-processing. A 125-h continuous test on stability of performance further corroborated the technical feasibility of the investigated process, establishing essentially a practical pathway to upgrade shale oil by using the as-generated methanol-reformed gas without removal of its containing CO₂ and steam as the hydrogen source.

本文研究了在固定床反应器下游的甲醇蒸汽重整装置上，采用NiMo/Al2O3催化剂对页岩油进行加氢脱硫，该装置提供含CO2和蒸汽的富h2气体。在380℃、4 MPa、气油体积比为600:1、油时空速为4.0 h−1的最佳加氢条件下，改造后的页岩油硫含量变化在4400 ppm左右，脱硫效率达到66%以上，符合国际船用燃料油标准（ISO 8217）。油的热值提高，密度和粘度降低，轻质油的含量增加，重质油的比例降低。通过对催化剂的表征，发现富h2气体中的水蒸气对加氢脱硫效率没有显著影响。水蒸气的存在不仅促进了重馏分的加氢裂化，而且减少了加氢过程中催化剂上的积碳。连续125小时的性能稳定性测试进一步证实了所研究工艺的技术可行性，基本上建立了一条实用的途径，即使用生成的甲醇转化气，而不去除其含二氧化碳和蒸汽作为氢源，来升级页岩油。

Aiming at enhancing the capture performance of electrostatic precipitator (ESP) for PM2.5 particles, this paper introduces a multi-field coupling model and carries out the analysis of the electromagnetic dedusting mechanism of four electric field ESP under the magnetic-field-induced trajectory modification, and investigates the capture performance of multiple electric field ESP for PM2.5 particles at different magnetic field introduction positions through numerical simulations and PIV (Particle Image Velocimetry) experiments. The PIV measurements showed flow-field patterns that were consistent with established ESP findings, where higher applied voltage and lower flue-gas velocity lead to stronger particle deflection toward the collection plate. These observed trends serve as a validation of the reliability of the present PIV setup and simulation model. Introducing a magnetic field into a specific zone resulted in particles to follow a spiral path leading to the collection plate. This motion not only altered the paths of particles in the targeted region but also influenced adjacent zones. Magnetic confinement was found to be more effective under low flue gas velocity and low operating voltage conditions. Furthermore, at lower voltages, the third electric field was more sensitive to magnetic confinement, whereas at higher voltages, the fourth electric field exhibited greater sensitivity. The findings can offer new design ideas for performance enhancement of traditional ESPs.

为了提高静电除尘器（ESP）对PM2.5颗粒物的捕集性能，本文引入了多场耦合模型，分析了四种电场的电除尘器在磁场诱导轨迹修正下的电磁除尘机理。通过数值模拟和粒子图像测速（PIV）实验，研究了不同磁场引入位置下多电场ESP对PM2.5颗粒的捕获性能。PIV测量显示的流场模式与ESP的发现一致，即较高的施加电压和较低的烟气速度会导致颗粒更强烈地向收集板偏转。这些观察到的趋势验证了当前PIV设置和仿真模型的可靠性。将磁场引入特定区域，导致颗粒沿着螺旋路径通向收集板。这种运动不仅改变了目标区域内粒子的路径，而且还影响了邻近区域。在低烟气流速和低工作电压条件下，磁约束更为有效。此外，在较低电压下，第3个电场对磁约束更敏感，而在较高电压下，第4个电场表现出更大的灵敏度。研究结果可为传统esp的性能提升提供新的设计思路。
