| Abstract: | Viscous separated and vortical flow surrounding a hemisphere cylinder has been computed by numerical solution of three dimensional compressible unsteady N S equations using the finite volume method and Runge Kutta time stepping scheme.Results are presented for the complex flow field structures including shocks,boundary layer,separated flow,vortical flow and their mutual effects. |

| Keywords: | hemisphere cylinder bodies numerical flow visualization separated flow vortices |
