Çinlar model at fully developed channel flow for Reτ = 2000

Large eddy simulation (LES), which is the numerical solution method of Navier-Stokes equation, is performed in a fully developed channel flow. In LES, Çinlar and homogeneous dynamic Smagorinsky models are used as subgrid-scale models and the results are compared with direct numerical solution (DNS)....

Description
Summary:Large eddy simulation (LES), which is the numerical solution method of Navier-Stokes equation, is performed in a fully developed channel flow. In LES, Çinlar and homogeneous dynamic Smagorinsky models are used as subgrid-scale models and the results are compared with direct numerical solution (DNS). A channel flow at Reynolds number Reτ = 2000 is computed using 192 × 64 × 48 mesh resolution. The results of Çinlar model are in good agreement with especially those of homogeneous dynamic Smagorinsky, even if the size of the grid is much coarser than the DNS resolution.
