Poisson-Nernst-Planck电泳模型的存在性理论

Existence theory for a Poisson-Nernst-Planck model of electrophoresis

Luciano Bedin, Mark Thompson

摘要:

研究了一个浸入不可压缩离子化流体中的带电刚性大分子的电泳运动模型。离子浓度由能斯特-普朗克方程与静电势的泊松方程、流体和大分子动力学的Navier-Stokes方程和牛顿方程耦合控制。利用Desjardins和Esteban [Comm. Partial Diff.等式,25(2000),1399- 1414]。

英文摘要:

A system modeling the electrophoretic motion of a charged rigid macromolecule immersed in a incompressible ionized fluid is considered. The ionic concentration is governing by the Nernst-Planck equation coupled with the Poisson equation for the electrostatic potential, Navier-Stokes and Newtonian equations for the fluid and the macromolecule dynamics, respectively. A local in time existence result for suitable weak solutions is established, following the approach of Desjardins and Esteban [Comm. Partial Diff. Eq., 25 (2000), 1399--1414].
