等离子体反应器流场的数值模拟

Numerical Simulation of the Flow Field in a Thermal Plasma Reactor

本文采用颗粒轨道模型对等离子体反应器进行数值模拟.数值格式用SIMPLER法.湍流模型用简单的次网格模型.计算结果给出速度场、温度场及颗粒轨道,对工程设计和工艺过程参数控制有参考价值。

A numerical simulation is presented for a thermal plasma reactor with particle-trajectory model in this paper. Turbulance is considered by using simple SGS model. The governing equations are solved by means of the algorithm of SIMPLER, The calculated results give the velocity and the temperature fields within plasma reactor, and the trajectories of the injected particles.
