RNGk−εModel由Yakhot和Orzag在1986年提出,称为重整化群k−ε模型(Renormalization Groupk−εModel)。 RNG k-epsilon Model中,通过在大尺度运动和修正后的黏度项体现小尺度的影响,而使这些小尺度运动有系统地从控制方程中去除。 RNGk−εModel的K方程和ε方程与标准k−ε模型类似: (1)∂(ρK)∂...
主要信息有,RNGkEpsilon继承自父类RASModel和BasicTurbulenceModel,模型参数包含 Cmu_; C1_; C2_; C3_; sigmak_; sigmaEps_; eta0_; beta_;出构造函数外,主要成员函数是返回k,epsilon,两个场有效扩散系数场的函数,最关键的一个函数就是求解湍流方程并修正湍流粘性系数的函数。 现在来看在.C文件中具体是怎么...
