摘要/Abstract

摘要： 用完全二维自洽模型计算等离子体的速度场与温度场,用颗粒轨迹模型计算颗粒的运动轨迹与加热历程,但在等离子体的连续、动量和能量控制方程中,增加一项由于颗粒直径、运动速度及能焓的变化而引起的源项,计及颗粒的运动与加热对等离子体的速度场与温度场的影响;在颗粒的运动轨迹与加热历程计算中,考虑流体阻力和热泳力对颗粒运动与加热的影响;并在等离子体的速度场与温度场和颗粒的运动与加热之间进行迭代计算。通过对铝颗粒与氩等离子体流的计算表明:颗粒与高频感应热等离子体流的相互作用不仅对颗粒的运动轨迹和加热历程有影响,而且对热等离子体流的速度场和温度场也有重要影响。

Abstract: The injection of alumina powders into an inductively argon plasma is simulated numerically.Attention is given to the plasma particle interaction and its effects on plasma fields and particle trajectory and thermal history.It is demonstrated that for most applications,such interactions must be considered in any model.

Key words: complete 2-D self-consistent rf plasma model, particle trajectory model, SIMPLER method, numerical iteration
