摘要

本文证明了基于圆柱体外部Navier-Stokes-Poisson-Nernst-Planck耦合系统的三维电流体动力学模型轴对称强解的全局存在唯一性。关键是我们利用函数的轴对称推导出Lp插值不等式,这使我们能够通过几种抵消定律对速度场和带电粒子建立各种先验估计。

GLOBAL AXISYMMETRIC SOLUTIONS TO THE 3D NAVIER-STOKES-POISSON-NERNST-PLANCK SYSTEM IN THE EXTERIOR OF A CYLINDER
In this paper we prove global existence and uniqueness of axisymmetric strong solutions for the three dimensional electro-hydrodynamic model based on the coupled Navier–Stokes–Poisson–Nernst–Planck system in the exterior of a cylinder. The key ingredient is that we use the axisymmetry of functions to derive the Lp interpolation inequalities, which allows us to establish all kinds of a priori estimates for the velocity field and charged particles via several cancellation laws.
