等离子体鞘层附近尘埃颗粒特性的数值模拟
Simulation of interaction between dust particles and plasma sheath and its distribution
摘要
Abstract
Collisionless steady plasma sheath model is taken into account to study the interaction between dusty particles and plasma sheath as well as the density distributions of electrons,ions and dusty particles.Numerical simulation results are obtained,showing that the ability of an isolated charge to absorb electrons weakens with the increase of dusty particle density and its temperature,while the collective effect strengthens with the radius of dusty particle.Simultaneously,Bohm velocity and the sheath thickness are also greatly affected.The sheath potential decreases significantly and the iJ-field is stronger near the electrode.In addition,the densities of electrons and ions reduce exponentially but the dusty particle has a critical value.The three particles satisfy the quasi-neutrality condition.关键词
