| 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. |

| Keywords: | multiple-time-scale turbulence model nonlinear numerical simulation |
