查询词典 turbulent

One is Bardina vorticity modification, and the other is Richardson number modification. Prediction results show that Bardina method has a superior capacity to Richardson number modification. Since DSM model has improved predictive results of the reversed velocity and tangential velocity, it is a potential method to predict strong swirling nonisotropic turbulent flow in stead of the longer convergence time.
