Abstract
Electroconvective flow between two infinitely long parallel electrodes is investigated via a multiphysics computational model. The model solves for spatiotemporal flow properties using two-relaxation-time Lattice Boltzmann Method for fluid and charge transport coupled to Fast Fourier Transport Poisson solver for the electric potential. The segregated model agrees with the previous analytical and numerical results providing a robust approach for modeling electrohydrodynamic flows.
摘要
通过多物理场计算模型研究了两个无限长平行电极之间的电对流流动。该模型使用双弛豫时间格子玻尔兹曼方法求解流体和电荷传输的时空流动特性，并与快速傅里叶变换泊松求解器耦合以求解电势。该分离模型与先前的分析和数值结果一致，为模拟电流体动力学流动提供了一种稳健的方法。
