Simulation of DC glow discharge plasma with free-moving dust particles in the radial direction
《Plasma Science and Technology》2023年第9期73-81,共9页田瑞焕 梁勇敢 郝书吉 冯杰 江晓楠 李辉 袁承勋 吴健 
supported by the Stable-Support Scientific Project of China Research Institute of Radiowave Propagation(No.132101W07);National Natural Science Foundation of China(No.12105251);National Key Laboratory Foundation Electromagnetic Environment(Nos.A382101001,A382101002 and A152101731-C02).
A self-consistent fluid model is developed to investigate the radial distributions of dusty plasma parameters in a DC glow discharge,in which the extended fluid approach of plasma particles and the transport equations...
