Abstract

The governing equations of the simulation are the Reynolels-averaged Navier-Stokes equa?tions and k-e model is adopted for turbulence flow. The numerical scheme is second order windward scheme. I he characteristics of flow field of ramjet assisted range projectile were simulated by a numeri-cal method. The results show that the air drag coefficient is not obviously changed at high supersonic and is increased at low supersonic and subsonic, wmch is caused by the pipelike structure in the projec?tile.
