摘要
采用非线性雷诺应力模式对双时间尺度紊流模型进行了修正 ,并将修正后的模型应用于具有回流的突扩流的紊流模拟中 。
A nonlinear multiple time scale turbulence model is derived by using a nonlinear Reynolds stress formula The modified model is used to simulate the flow over a backward facing step by finite volume method, the computed results are well agreement with the test data and much better than that of the multiple time scale turbulence model
