本文提出了一种用于模拟感应等离子体中流体流动和传热的二维电磁场k-ε湍流模型。与以前的研究使用一维电磁场表示进行了比较分析。结果表明，同时存在层流和湍流状态的放电。本模型被发现，以科普这种变化，在当地的层流/湍流扩散，并可用于预测的流量和温度场的细节，主要是层流（低雷诺数）或湍流（高雷诺数）条件下的放电。
This paper describes a k- epsilon turbulent model with two-dimensional representation of electromagnetic fields for the simulation of fluid flow and heat transfer in an induction plasma. A comparative analysis is made with an earlier study using one-dimensional electromagnetic fields representation. The results reveal the simultaneous presence of both laminar and turbulent flow regimes in the discharge. The present model was found to cope well with such variations in the local laminar/turbulent diffusivity and could be used to predict the details of the flow and temperature fields in the discharge under predominantly laminar (low Reynolds number) or turbulent (high Reynolds number) conditions.
