| Abstract: | A three-dimensional model was applied to predict the temperature,velocity and air concentration distribution of an argon plasma jet issuing into air atmosphere.Calculated results were validated with the experimental 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. |

| Keywords: | plasma jet operating parameters heat transfer and fluid flow simulation |
