Abstract:
The performance of the Smagorinsky eddy-viscosity subscale grid model and the suitability of second-order accurate finite volume scheme for large eddy simulations of complex flows are investigated in the case of turbulent wake behind a nominally two-dimension cylinder at subcritical Reynolds number 20000 based on freestream velocity and cylinder diamter. The numerical method is applied to the incompressible Navier-Stokes equation written in generalized nonorthogonal coordinates, which has the following main...
