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.

Key words: hemisphere cylinder bodies, numerical flow visualization separated flow, vortices
