NUMERICAL SIMULATION OF HYPERSONIC LAMINAR WAKE FLOW

The hypersonic laminar wake flow behind spherically blunted cone is studied by solving Navier-Stokes equations with NND schemes (Non oscillatory, containing no free parameters and dissipative scheme). The bow shock, corner expansion fan, wake shock and free layer in the wake region are captured successfully. The calculated pressure, temperature and velocity distributions along the wake centerline agree with experimental date satisfactorily. Especially, the history of vortex in the recirculation region start...
