摘要

这一贡献的目的是详细阐述了模拟流动的双离子电解质通过多孔压电介质的一般框架。利用双尺度渐近展开的方法,导出了描述该结构电动力学的宏观现象学方程,并给出了有效力学系数和有效非力学系数的计算公式。在压电骨架与导电流体的交界面上假定有自然跳跃条件。

Flow of electrolyte through porous piezoelectric medium: macroscopic equations

The aim of this contribution is to elaborate a general framework for modelling flows of two-ionic species electrolytes through porous piezoelectric media.

By using the method of two-scale asymptotic expansions, the macroscopic phenomenological equations describing electrokinetics of such a structure are derived and the formulae for the effective mechanical and nonmechanical coefficients are given. Natural jump conditions are assumed on the interfaces between the piezoelectric skeleton and conductive fluid.
