Three-dimensional numerical simulation of arbitrary configuration and surface-modified dust particles charging process in plasma

摘要：

　　We have established a three-dimensional numerical simulation method to simulate the charging process of dust particles in plasma.The method is based on Particle-in-Cell(PIC)technique,which can mesh a plasma region containing particles with arbitrary configuration.The innovative point of our method is that it can be applied to surface-modified dust particles,including electrophilic and dielectric properties modification.In addition,the boundary flow injection conditions in several typical scenarios are also considered.This method realizes a three-dimensional numerical simulation of arbitrary configuration and surface-modified dust particles charging process in plasma.
