摘要
在k-ε模型的体系内,从若干约束条件出发,给出雷诺应力与平均速度梯度之间较通用的模型公式。并用槽道流动中有关的实验数据确定出模型公式中包含的系数。最后用方截面管流中有关二次流的实验结果对模型进行鉴定。结果表明,给出的模型在槽道流动和方截面管流中都获得了满意的结果。
A more general relation between Reynolds stress and mean velocity gradient is given for k-ε turbulent model under some restricted condintions. The modeling coefficient are found from experimental data of channel flows. Then the normal Reynolds stresses in square duct flow are calculated using the new model and coefficient functions, the results are consistent with the experimental data.
