双时间尺度紊流模型的非线性修正与验证

Non-linear revision of multiple-time-scale turbulence model and its verification

  • 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,其计算结果比采用双时间尺度紊流模型有进一步的改进。

     

    Abstract: 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 wel agreement with the test data and much better than that of the multiple-time-scale turbulence model.
