dc.description.abstractComputational simulations of turbulent flows around a circular cylinder were performed to investigate the drag coefficient and Strouhal number at sub-critical and critical Reynolds numbers. Unstructured grids with 3.1 million cells including prism layers were used in the present study. Both RANS and PANS simulations using k-ω SST model failed to predict a transitional behavior of drag coefficient and vortex shedding frequency at sub-critical and critical Reynolds numbers due to the absence of laminar separation bubble. But a hybrid combination of unresolved turbulence viscosity in PANS and sub-grid scale turbulence viscosity in LES provided a good agreement of drag coefficient and vortex shedding frequency with previous results.-
