摘要:In this talk, I will show two parts of our recent work on Poisson-Nernst-Planck system.

The first part is the asymptotic solution of 1D steady state Poisson-Nernst-Planck system with multi-ions. This asymptotic solution is based on the classical matched asymptotic technics.

This part is based on the work

X. Wang, D. He, J. Wylie, H. Huang, Singular perturbation solutions of steady-state Poisson-Nernst-Planck systems, Physical Review E, 89, 022722, 2014.

The second part is the energy preserving numerical methods for the unsteady Poisson-Nernst-Planck system by using both the finite difference method and finite element method.

This part is based on the following work

1. D. He and K. Pan, An energy preserving finite difference scheme for the Poisson-Nernst-Planck system. Applied Mathematics and Computation, 287-288(5) (2016) 214-223.

2. H. Gao and D. He, Linearized Conservative Finite Element Methods for the Nernst-Planck-Poisson Equations. Journal of Scientific Computing, 72(3) (2017) 1269–1289.

个人介绍:
