Numerical simulation of a pulsating flow arising over an axisymmetric spiked blunt body at Mach 2.21 and Mach 6.00

The present paper reports a numerical simulation of the supersonic/hyperson ic unsteady flow over a spiked blunt body. Axisymmetric compressible Navier -Stokes equations are solved using a high resolution unfactored implicit up wind Poe's scheme and a time-accurate pseudo-time method is employed for ad vancing in time. Unsteady flows arising at Mach 2.21 and Mach 6.00 around a spiked cylinder are simulated and the computational results are compared w ith measurements. The simulated results are used to increase understanding of the mechanisms of the flow.
