| 摘 要： | 本文对有反向载气注入条件下等离子体反应器内的传热与流动特性进行了二维数值模拟.数值计算结果表明,由于反向载气的注入,在等离子体发生器喷嘴出口与载气喷口之间的空间区域会形成一个滞止层,而且该滞止层的位置随着反向注入的载气速度(流量)的增加向等离子体发生器出口移动,数值模拟结果与实验观察结果定性一致.

| Abstract: | In this paper,a two-dimensional modeling of heat transfer and fluid flow in a counter- flow plasma reactor is conducted.The calculated results show that a stagnation layer can be formed between the anode nozzle of the plasma torch and the injection port of the carrier gas due to the counter injection of the cold carrier gas;and the position of the stagnation layer can be pushed toward the torch nozzle exit with increasing the injection velocity(or flow rate)of the carrier gas.The modeling results are qualitatively in agreement with experimental observations. |
