摘要
将3种版本的RNG k-ε湍流模型应用于轴对称冲击射流场的数值模拟.通过与实验结果的比较,考察了模型系数的改变和非线性附加项对数值结果的影响,评价了三种模型对冲击射流的数值预测能力.
Three versions of RNG based k-ε turbulence models have been applied to an axisymmetric turbulent impinging jet flow. By comparison with the experimental data, the effects of modifications of model coefficients and the introduction of non-linear additional term on numerical results are examined, and the numerical predictive abilities of the three models on impinging jet flow are also assessed.
