摘要
应用大气压热等离子体射流传热与流动的三维数学模型,预测了氩等离子体射流射入空气环境时的温度、速度及卷吸空气质量分数分布,并与文献中同等条件下的实验结果进行了比较,结果相吻合.在此基础上,分析了射流入口温度和速度变化、工作气体中添加高导热系数气体以及液料注入对射流卷吸环境空气和热等离子体射流传热与流动过程的影响.
A three-dimensional model was applied to predict the temperature.velocity and air con- centration distribution of an argon plasma jet issuing into air atmosphere. Calculated results were validated with the experirnental results under the same operating conditions. The effects of the inlet velocity inlet temperature, working gas additionally filled with high thermal conductivity gas and the injection of sprays on the air entrainment as well as the heat transfer and fluid flow of the plasma jet were investigated.
