基于COMSOL Mutiphysics的粒子悬浮效果模拟仿真研究
|
Abstract:
粒子悬浮是指固体粒子在液体或气体中不断运动并保持悬浮状态的现象，这个现象广泛存在于许多工程和科学领域。而粒子悬浮模拟可以通过数值模拟的方式对粒子悬浮行为进行深入研究和分析，揭示粒子与流体之间的相互作用机制。本研究利用COMSOL Mutiphysic仿真软件中流体流动模块中的单相流与粒子追踪功能，对粒子在液体中的悬浮行为进行了数值模拟。通过建立粒子与流体之间的相互作用模型，探讨了粒子在不同流体条件下的运动特性，并分析了粒子浓度、粒子尺寸等因素对悬浮行为的影响。通过仿真结果与实际悬浮测试效果进行对比，研究结果对于理解粒子悬浮系统的稳定性和传输特性具有一定的参考价值。
Particle suspension refers to the phenomenon where solid particles continuously move and remain suspended in a liquid or gas medium. This phenomenon is widely observed in various engineering and scientific fields. Simulation of particle suspension allows for in-depth study and analysis of par-ticle behavior, revealing the mechanisms of interaction between particles and the surrounding fluid. In this study, numerical simulation of particle suspension in a liquid was conducted using the sin-gle-phase flow and particle tracking capabilities within the fluid flow module of COMSOL Multiphys-ics simulation software. By establishing an interaction model between particles and the fluid, the movement characteristics of particles under different fluid conditions were investigated, and the effects of particle concentration and size on suspension behavior were analyzed. The simulation re-sults were compared with actual suspension tests, providing valuable insights into the stability and transport properties of particle suspension systems.
