Abstract

The dynamic two-parameter Clark model (DTCM) was analyzed, for its efficiency to overcome the inapplicability of the dynamic one-parameter Clark model (DCM), for application to turbulent channel flows. The predictions of large eddy simulation (LES) with the DTCM were compared with those of DSM. It was found that the DTCM overcame the defects of the DCM model by diminishing the negative effective viscosity in the viscous sublayer for the tensor diffusivity term. The actual LES showed that the prediction of DTCM for the turbulent channel flows at Reτ=590 was similar to that of the dynamic Smagorinsky model.
