摘要

压强和微波功率是高气压空气微波放电中的两个重要影响因素, 取值对放电过程中等离子体动力学特征及自组织结构有着直接的影响. 利用有效扩散模型和双重网格方法,对放电过程中压强和微波功率的影响进行了数值研究. 结果表明, 压强降低时放电等离子体将从间隔分明的等离子体斑点结构变为一团呈扩散特性的等离子体, 而微波功率增大时,等离子体向着微波入射方向的传播速度随之快速增大, 传播过程中等离子前沿的跳跃性和斑点状的自组织结构也更加分明.

Abstract

Pressure and microwave power are the most important parameters during microwave breakdown in air and affect the self-organization plasma pattern structure and its propagation directly. In order to study the effects of pressure and microwave power, an effective-diffusion fluid plasma equation is solved together with Maxwell's equations, and the double grid method is also used to meet the different grid size requirement of plasma equation and finite-difference-time-domain for Maxwell's equations. The numerical results show that with lower pressure the plasma behaves as a more diffuse plasmoid instead of a well defined plasma pattern structure under higher pressure, and the increase of incident microwave power will lead to a rapid growth of the front propagation velocity and a well separated and sharp pattern structure, and the higher incident power also results in jump-like front propagation.
