标题： Effect of Couette Flow on Electroconvective Vortices

摘要： 电极之间无限长电极存在库埃特流时，对电渗涡旋行为的数值模拟进行了研究。 具有快速泊松求解器的两弛豫时间格子玻尔兹曼方法用于求解流场、电场和电荷密度的时空分布。 在建立电渗涡旋后，将库埃特横向流动应用于解中。 增加横向流动速度会改变涡旋，并在剪切应力达到临界值时最终抑制它们。 显示英文摘要

摘要： Numerical simulation of Electroconvective vortices behavior in the presence of Couette flow between two infinitely long electrodes is investigated. The two-relaxation-time Lattice Boltzmann Method with fast Poisson solver solves for the spatiotemporal distribution of flow field, electric field, and charge density. Couette cross-flow is applied to the solutions after the electroconvective vortices are established. Increasing cross-flow velocity deforms the vortices and eventually suppresses them when threshold values of shear stress are reached.
