| Abstract |
The asymptotic behavior and the performance of the dynamic Clark model with an anisotropic filter are analytically and numerically revealed in comparison with the dynamic Smagorinsky model and the dynamic mixed model. In the dynamic Clark model, the change of the isotropic filter-width for the Clark term to the anisotropic one makes it possible to apply to turbulent channel flows. Then, the near-wall scaling of the model coefficient for the dynamic Clark model is also corrected as y3. The performance of the dynamic Clark model is the almost same as that of the dynamic mixed model, which is better than the dynamic Smagorinsky model.
