Abstract�� The transonic turbulent flow around a blunt nosed and short body at large angle of attack was calculated and analysed by using numerical simulation method to solve the full N-S equations. In the computation, Van Leer's scheme was used to discretize the inviscid flux terms and a new limiter function was constructed to realize TVD character. The viscous flux terms were discretized by using a central difference scheme. The Baldwin-Lomax turbulent model was used in the viscous terms. Numerical results qualitatively show that the separated flow has an unsteady quasi-periodic character.
Keywords�� transonic velocity   separated flow   non-steady flow   a blunt nosed short body
