基于格子Boltzmann方法的电流变液动力学建模及数值模拟
Dynamic modeling and numerical simulation of electro-rheological fluids based on Lattice Boltzmann Method
摘要
Abstract
Since the fast response of the internal structure of the electro-rheological (ER)suspension fluids occur in the controlled space (electrode distance is generally 1 mm~2 mm)of the applied electric field,where the main feature of the ER suspension fluids in the certain time and spatial scales is low shear rate but high flow resistance,which means the Mach number and the Reynolds number are generally small,it can be considered as micro-scale flow.According to this characteristic,the author proposed a discrete-particle-motion model of the ER suspension flows based on the Lattice Boltzmann Method(LBM)of the Mesoscopic kinetic theory.The results of the dynamic simulation showed that the model solved the problem of describing the changes of the rheological properties of some local flow fields and the influences on the particle movement during the two-way coupling in this flow field.关键词
