摘　　要：k-ε模型及其双方程模式成功应用于湍流场的流动分析,并使湍流流动的质量、动量、能量基本方程组可以统一表达。SIMPLE算法是流体流场数值模拟的最重要方法。通过VC和MATLAB的混合编程用SIMPLE算法,实现了湍流场的数值模拟。基于SIMPLE算法对一个热流交汇扩散的问题做了数值求解,展示了内部湍流场的分布情况。k-ε Turbulence Model and its two-equation mode have been successfully used for turbulent flow analysis, and make the basic turbulent flow equations of mass, momentum, energy able to be expressed together. SIMPLE algorithm is the most important method for the numerical simulation of fluid flow. The mixed programming with Visual C＋＋ and MATLAB through SIMPLE algorithm from a numerical simulation for turbulent flow field. Finally, a simulation of proliferation of heat intersection is made ,and the turbulent flow distribution is described in detail.
