In this paper, three solar stills with similar geometries are numerically investigated for analysis and comparison. The solar stills include single slope, V-type, and greenhouse stills. Steady-state laminar flow numerical simulations with different water surface temperatures and cover glass temperatures are performed. Simulation results were confirmed with data from analytical and experimental models to ensure reliability. The results showed that the V-type still has a higher number of recirculation zones than that of single slope and greenhouse stills. These vortex regions are small, but the velocity magnitude is no less than the other two stills. This difference makes the freshwater yield and convection heat transfer coefficient of V-type still the largest. Daily freshwater productions of single slope, V-type, and greenhouse stills are 0.592, 0.673, and 0.623 kg/m2, respectively. Productivity at 15 PM is 2.5 times higher than the hours from noon to 14 PM. The natural convection heat transfer coefficient seemed to be unvaried with the temperature difference but changed strongly with the still geometry.
本文对具有相似几何形状的三种太阳能蒸馏器进行了数值研究,以进行分析和比较。这些太阳能蒸馏器包括单坡、V 型和温室蒸馏器。在不同的水面温度和盖板玻璃温度下进行了稳态层流数值模拟。模拟结果与分析和实验模型的数据进行了确认,以确保可靠性。结果表明,与单坡蒸馏器和温室蒸馏器相比,V 型蒸馏器有更多的再循环区。这些漩涡区很小,但速度大小不亚于其他两种蒸馏器。这一差异使得 V 型蒸馏器的淡水产量和对流换热系数最大。单坡、V 型和温室蒸馏器的日淡水产量分别为 0.592、0.673 和 0.623 公斤/平方米。下午 15 时的生产率是中午至下午 14 时的 2.5 倍。自然对流传热系数似乎与温差无关,但与蒸馏器的几何形状有很大关系。

Stirred tanks are widely used in the industrial world, design and improvements are still being developed, including the stirred fermenter tank. A numerical study was carried out to examine the relationship between experimental and reference and computational analysis, in order to minimize the power consumption of a stirred fermenter tanks and optimize the velocity distribution and its profile in radial and axial direction. Specifically, velocity distribution profile in radial and axial direction and the profile of pressure distribution of an experimental impeller, a flat impeller, and a flat-hole impeller were investigated using Computational Fluid Dynamic (CFD) analysis. It was found that the axial velocity at the top and the bottom of the experimental impeller was highly disparate at around 0.95 m/s, while the flat impeller and the flat-hole impeller experienced a disparity of 0.05 m/s and 0.21 m/s, respectively. In case terms of decreased power, the experimental impeller showed power reduction of 21%, greater than that of the flat-hole impeller configuration of 17%.

Heat exchangers are commonly utilized to transfer heat between two fluids in a number of industries. However, parameters such as fluid flow velocity, temperature difference, and thermal conductivity limit their efficiency. Researchers have investigated the use of nanofluids - fluids containing nanoparticles that boost thermal characteristics - to improve the performance of heat exchangers. The use of nanofluids can improve the efficiency of double-pipe heat exchangers. However, research on the influence of TiO2/water nanofluid on the performance of double-pipe heat exchangers is insufficient. The purpose of this research is to investigate the impact of TiO2/water nanofluid on the efficiency of a double-pipe copper counter-flow heat exchanger. A double-pipe copper counter-flow heat exchanger using cold (room temperature) and hot (70°C) water as working fluids was used in an experimental investigation. They created nanofluids by adding varying concentrations (0.1%, 0.3%, and 0.5%) of TiO2 nanoparticles to water and measuring their heat conductivity and viscosity. They then calculated the overall heat transfer coefficient and efficacy by measuring the input and outlet temperatures as well as the flow rates of both fluids. It was discovered that adding TiO2 nanoparticles to water enhanced its heat conductivity and viscosity substantially. The overall heat transfer coefficient increased up to 0.3% but declined at 0.5% nanoparticle concentration. At a nanoparticle concentration of 0.3%, the maximum effectiveness was attained, with a corresponding increase in efficiency of up to 23%. The scientists found that using TiO2/water nanofluid to improve the efficiency of double-pipe heat exchangers is a viable option.
在许多行业中,热交换器通常用于在两种流体之间传递热量。然而,流体流速、温差和热导率等参数限制了它们的效率。研究人员已经对纳米流体(含有纳米颗粒的流体,可增强热特性)的使用进行了研究,以提高热交换器的性能。使用纳米流体可以提高双管热交换器的效率。然而,有关 TiO2/水纳米流体对双管热交换器性能影响的研究还不够充分。本研究旨在探讨 TiO2/纳米水流对双管铜逆流热交换器效率的影响。实验研究使用了一个双管铜逆流热交换器,以冷水(室温)和热水(70°C)作为工作流体。他们在水中加入不同浓度(0.1%、0.3% 和 0.5%)的二氧化钛纳米粒子,并测量其导热系数和粘度,从而制造出纳米流体。然后,他们通过测量两种流体的输入和输出温度以及流速,计算出总体传热系数和效率。结果发现,在水中添加 TiO2 纳米粒子可大幅提高水的导热性和粘度。整体传热系数在 0.3% 时有所增加,但在纳米粒子浓度达到 0.5% 时有所下降。当纳米粒子浓度为 0.3% 时,效果达到最大,效率也相应提高了 23%。科学家们发现,使用 TiO2/水纳米流体来提高双管热交换器的效率是一种可行的选择。

The fisheries sector is one of the potential sectors that contribute to Indonesia's state income, but it has often been neglected. Almost all fishing boats still use diesel engines as the main power source to propel the boat. The use of this type of fuel has an impact on increasing the level of air pollution such as CO2, SO2, and NOX in the atmosphere. However, research to reduce ship pollution, especially the combination of propulsion system for fishing boats using engines and sails, is rarely carried out. This study aims to determine the hydrodynamic characteristics of fishing vessels on the north coast of Java due to the application of numerical variations in laying sails using Computational Fluids Dynamics (CFD). The numerical simulation results show that the placement of sails in each model variation results in a change in the fluid flow pattern from bow to stern which can contribute to fuel efficiency. From the comparison of the three models, the most effective placement of sails is at the bow of the ship.
渔业部门是为印尼国家收入做出贡献的潜在部门之一,但却常常被忽视。几乎所有渔船仍然使用柴油发动机作为推动船只的主要动力源。这种燃料的使用会增加大气中的二氧化碳、二氧化硫和氮氧化物等空气污染。然而,减少船舶污染的研究,特别是渔船使用发动机和风帆组合推进系统的研究,却很少开展。本研究旨在利用计算流体动力学(CFD)确定爪哇岛北海岸渔船在铺设风帆时因数值变化而产生的水动力特性。数值模拟结果表明,每个模型变化中的风帆布置都会导致从船头到船尾的流体流动模式发生变化,从而有助于提高燃油效率。通过对三种模型的比较,最有效的船帆布置位置是船头。

Computational Fluid Dynamics (CFD) software is well known for its application feasibility as well as reliable results in modeling electrochemical, thermal, and fluid transport processes. CFD has been used to investigate the phenomena involved in the operation of fuel cells, providing a large amount of data that must be analyzed to improve cell efficiency. This paper aims to demonstrate that programming can be used in the post-processing phase, using scripts in Python language to automate data analysis, based on the results of the simulation of oxygen transport in Polymer Electrolyte Membrane Fuel Cell (PEMFC). The OpenFOAM open-source CFD tool solved the fluid governing equations through the SIMPLE algorithm of three proposed Gas Diffusion Layer (GDL) case studies. In this work, an algorithm is presented to extract, compute and visualize the post-process results, supporting the GDL selection.

Waterjet Technology has been used vastly in our world nowadays due to its advantages and it can be implemented in many industrial sectors or even in the medical sector and food industry sector. Nozzle is a component that has been utilized in waterjet which is employed in a wide range of engineering applications to control the rate of flow, velocity, and the jet pressure of the water. This paper discusses the CFD analysis on a pure waterjet nozzle to obtain the output of the water that jets out from three different diameters of nozzle and select the effective nozzle diameter to be used for the fruit peeling and cutting process. The pressure used for the analysis are 200MPa, 300MPa and 400MPa, which was analysed for three different nozzle diameter 0.76mm, 1.02mm and 1.27mm. From CFD analysis, it is established that as the pressure loss of the water jet increases, the outlet velocity of the jet increases. Furthermore, for fruit peeling and cutting process the impact angle of the nozzle should be prioritised as the peeling of the fruit should be smooth and even before cutting the fruit. Thus, the most suitable parameters were found to be 400MPa and 1.02mm of pressure and nozzle diameter respectively. This will allow for the intended fruit cutting process with a stand-off distance that can be ranged from 1mm to 9mm.
水刀技术因其优势在当今世界得到了广泛应用,它可以应用于许多工业领域,甚至是医疗和食品行业。喷嘴是水刀中的一个部件,在广泛的工程应用中被用来控制水的流速、速度和喷射压力。本文讨论对纯水射流喷嘴进行 CFD 分析,以获得从三个不同直径的喷嘴喷射出的水的输出量,并选择用于水果去皮和切割过程的有效喷嘴直径。分析使用的压力分别为 200MPa、300MPa 和 400MPa,并对 0.76mm、1.02mm 和 1.27mm 三种不同直径的喷嘴进行了分析。CFD 分析表明,随着水射流压力损失的增加,水射流的出口速度也随之增加。此外,在水果去皮和切割过程中,喷嘴的冲击角度应优先考虑,因为在切割水果之前,水果去皮应平滑均匀。因此,最合适的参数分别是 400MPa 的压力和 1.02mm 的喷嘴直径。这样就能实现预期的水果切割过程,其间距可从 1 毫米到 9 毫米不等。

The mixing of fuel and air plays a major role in the spray and flame behavior, hence affecting the combustion performance and emissions of the internal mixing air-assisted atomizers. Air-assisted atomizers are introduced to counter the low-pressure differential of a simplex nozzle, which reduces the atomization quality. The present study aims to determine the effects of Multi Circular Jet (MCJ) plates on the geometrical configurations of internal flows in mixing chamber and the internal flow of plate 3 using different properties of fuel. In this study, the realizable k-ε turbulence model, specifically designed for strongly swirling flows, is validated through numerical simulations. The turbulence model selected is a type of Reynolds averaged Navier-Stokes (RANS) model called the k-ε model. The MCJ plates provide the primary air entrance into the mixing chamber. Additionally, it acts as a turbulence generator and can be adjusted to alter the flow of fuel and air mixtures in a mixing chamber. The study compares several MCJ geometries in terms of pressure, speed, turbulent kinetic energy, and volume fraction and compares the performances of diesel and Crude Palm Oil (CPO) B30 biodiesel fuels. The findings imply that CPO B30 biodiesel has superior atomization and mixing due to its higher density and turbulent kinetic energy. CPO B30 biodiesel was compared to Diesel in terms of maximum pressure, average speed, turbulent kinetic energy per unit mass, and volume fraction. The results indicate that CPO B30 has lower pressure and higher velocity than Diesel, suggesting better fuel atomization and mixing. The higher density of CPO B30 leads to increased turbulent kinetic energy, improving fuel-air mixing inside the combustion chamber. The study demonstrates that the use of MCJ plates can enhance mixing in a mixing chamber. In addition, MCJ plates show the ability to control the spray and atomization. The findings of this study contribute to a better understanding of the relationships between geometry and fuel-air mixing, as well as the characteristics of the internal mixing air-assisted atomizer, which will lead to future burner system improvements.
燃料和空气的混合在喷雾和火焰行为中起着重要作用,从而影响内部混合空气辅助雾化器的燃烧性能和排放。引入空气辅助雾化器是为了消除单喷嘴的低压差,因为低压差会降低雾化质量。本研究旨在确定多环形喷射板(MCJ)对混合室内部流动几何配置的影响,以及使用不同性质燃料时板 3 内部流动的影响。本研究通过数值模拟验证了专为强漩涡流设计的可实现 k-ε 湍流模型。所选的湍流模型是一种雷诺平均纳维-斯托克斯(RANS)模型,称为 k-ε 模型。MCJ 板是进入混合室的主要空气入口。此外,它还充当湍流发生器,可通过调节来改变混合室中燃料和空气混合物的流动。研究比较了压力、速度、湍流动能和体积分数方面的几种 MCJ 几何结构,并比较了柴油和粗棕榈油 (CPO) B30 生物柴油燃料的性能。研究结果表明,由于 CPO B30 生物柴油的密度和湍流动能更高,因此其雾化和混合效果更好。CPO B30 生物柴油与柴油在最大压力、平均速度、单位质量湍流动能和体积分数方面进行了比较。结果表明,与柴油相比,CPO B30 的压力更低,速度更高,表明燃料雾化和混合效果更好。CPO B30 的密度较高,导致湍流动能增加,从而改善了燃烧室内燃料与空气的混合。这项研究表明,使用 MCJ 板可以增强混合室中的混合效果。此外,MCJ 板还显示出控制喷雾和雾化的能力。这项研究的结果有助于更好地理解几何形状与燃料-空气混合之间的关系,以及内部混合空气辅助雾化器的特性,这将有助于未来燃烧器系统的改进。

Investigation of Sloshing in Different Tank Shapes using Smoothed Particle Hydrodynamics 基于光滑粒子流体力学的不同槽形晃动研究

Sloshing is the violent motion of a resonant fluid in a moving tank; when the fluid moves and interacts with the tank, the dynamic pressure from such an interaction can cause large fluid deformations with tank walls. In this study, a 3D numerical simulation of sloshing was carried out with five variations of the tank model, i.e., prismatic, rectangular, tube, spherical, and the new model tank with a filling ratio of 25% and 50%. Forced oscillation motion in a roll used frequencies 1.04 Hz and 1.34 Hz. The amplitude of movement was 8.66°. One pressure sensor was used to measure dynamic pressure in the mid of the tank. Because sloshing deals with large deformation and discontinuities, the particle method was suitable for the application. This study used smoothed particle hydrodynamics based on weakly compressible SPH (WCSPH). SPH is a Lagrangian meshless method known as mesh-free computational fluid dynamics. Open-source SPH solver version 5.0 was used to reproduce sloshing in different tank shapes; in addition, advanced visualization was performed using the VisualSPHysics add-on in Blender version 2.92. The sloshing visualization is more realistic and attractive than conventional SPH post-processing. The results of this study indicate that different tank shapes influence reducing the value of dynamic pressure and hydrodynamic force. It is found that a practical tank shape is a tube tank and a new model tank with a reduced dynamic pressure value of 9% and 11% and a reduced hydrodynamic force value of 36% and 48%.
晃动是运动槽中共振流体的剧烈运动;当流体运动并与储罐相互作用时,这种相互作用产生的动压力会导致流体与储罐壁发生较大的变形。在本研究中,采用棱柱形、矩形、筒形、球形以及填充率为25%和50%的新型油箱五种不同的油箱模型,进行了晃动的三维数值模拟。横摇中的强迫振荡运动使用的频率为1.04 Hz和1.34 Hz。运动幅度为8.66°。一个压力传感器用于测量罐体中部的动态压力。由于晃动处理的是大的变形和不连续性,因此颗粒法适合应用。本研究采用基于弱可压缩SPH (WCSPH)的光滑粒子流体力学方法。SPH是一种拉格朗日无网格方法,称为无网格计算流体动力学。开源SPH求解器5.0版本用于再现不同槽形的晃动;此外,使用Blender 2.92版本中的visualspphysics插件执行高级可视化。晃动可视化比传统的SPH后处理更加逼真和吸引人。研究结果表明,不同的水箱形状对动压力和水动力的减小值有影响。研究发现,实用的罐型是管式罐和新型罐,动压值分别降低9%和11%,水动力值分别降低36%和48%。
