| Abstract | Numerical flow analysis at Reynolds number 1.410and 8.010 over a circular cylinder is carried out in this work. The comparison of the pressure coefficient over the surface of circular cylinder is carried out with the experimental data for these Reynolds numbers. Comparisons of computed Reynolds stresses are carried out with experimental data for DES and DDES. For massively separated flows, the resolved stresses have much bigger contribution than modelled stresses. A comparison of the modelled and resolved stresses is made at the Re= 810 to appreciate their contribution. It is pointed that the contribution from both modelled and resolved Reynolds stresses give a better overall view of the Reynolds stresses of the flow. . |
