In a laboratory setup a horizontal rod is heated on one side. By natural convection a stable temperature pattern is developed. Using the Nusselt formulation of the natural convection of cylindrical rods, the temperature distribution can be calculated. Only a good match of the simulations ... Read More
The annular reactor is a very useful design to carry many chemical reactions. In this study, COMSOL Multiphysics® software was used to study the isothermal mass transfer from the inner side of the outer tube of the annular reactor in the range of 200 Read More
Horizontal-Flow Constructed Wetlands (HFCWs) are a particular type of biofilter, and as such they rely mostly on the activity of bacterial communities to treat wastewater. Bacterial growth in HFCWs induces dramatic changes in its hydraulic and hydrodynamic behaviour (bioclogging), which ... Read More
The current work is dedicated to develop a FEM model for compressors using moving mesh. An analytical model is already developed for a classic compressor based on mass and energy balance and is extended to a finned piston compressor. COMSOL Multiphysics® is employed to verify the ... Read More
Introduction: One of the main characteristic of the superconductors is its diamagnetic response of applied magnetic fields. The superconductors refuse the penetration of magnetic field into its interior, it is the well know Meissner effect, B=0 into the superconductor sample. However ... Read More

优先流作为结构性土壤水分入渗的主要方式，影响着作物对降水以及灌溉用水的利用效率，同时影响污染物在土壤中的迁移过程。虫洞等大孔隙是产生优先流的重要因素，准确评估优先流运动对于土壤入渗的研究具有重要意义。本文主要借助COMSOL Multiphysics软件，探索虫洞的存在对土壤水分入渗的影响。我们结合熔锡灌注法和三维激光扫描法，从田间土壤中提取到真实的虫洞三维结构，然后将真实的虫洞3D结构导入COMSOL5.5中，构建土壤入渗模型。该模型主要用到多孔介质和地下水流模块的理查德方程，其中土体主要由虫洞和土壤基质两部分构成 ... Read More
晶粒细化可有效减少金属凝固组织内部缺陷、提升产品质量。在钢铁冶金领域，通过脉冲磁场干预金属凝固过程以促使凝固组织发生细化是一类常见的手段。近年来人们针对脉冲磁场细晶机制提出诸多机理，为了揭示哪种或哪些机理起主要作用，有必要对脉冲磁场作用下金属熔体内部电磁效应进行研究。本文利用COMSOL Multiphysics中的磁场、流场（k-ε）和动网格技术，对模铸和连铸条件下脉冲磁场在圆柱形金属熔体内产生的磁场、感应电流、电磁力和流场进行仿真模拟研究。研究揭示了电磁场随时间演变规律，以及熔体在电磁力作用下的流动规律。研究表明磁场主要以竖直分量为主 ... Read More
摘要：本文通过数值模拟分析研究了高效空气过滤器的阻力与PPI、滤纸褶高之间的关系。研究表明，在一定条件下，增加PPI和增加滤纸褶高都可以增大过滤面积，减小滤纸阻力，但同时会增大高效空气过滤器结构阻力，因此滤纸存在最佳的PPI或褶间距和褶高使过滤器的阻力最低。不同的滤纸有不同的最佳结构参数。本文采用数值模拟方法对高效过滤器的阻力进行模拟，经与实测数据对比表明，误差低于10%，模拟方法可行。同时，通过对某款滤纸制成的高效过滤器进行了模拟分析，讨论了PPI和褶高对高效过滤器阻力的影响。最后建立了通用数值分析方法，通过更改相关设定参数，快速计算高效过滤器的阻力 ... Read More
