摘要/Abstract

摘要： 对Masselot and Chopard提出的模拟气固两相流动的格子Boltzmann-格子气(LBE-LGA)方法进行推广,能够反映两相间拖曳作用.利用该方法研究封闭方腔内的气固两相流运动特性,分析斯托克斯数St和模拟颗粒数目对颗粒群运动的影响,并与文献结果进行比较,表明LBE-LGA方法模拟颗粒运动是可行的.

关键词: 气固两相流, 微细颗粒物, LBE-LGA方法

Abstract: We present an extension of lattice-Boltzmann-lattice-gas method proposed by Masselot and Chopard for gas-solid flows,in which the drag force between gas and solid is considered.The method is applied to particles in a driven cavity flow.Effects of Stokers number and total number of particles are analyzed.Simulation results are compared with previous works.It shows that the proposed LBE-LGA method can serve as a promising tool for simulating gas-particle flows.

Key words: gas-solid flow, microparticle, lattice Boltzmann method
