NUMERICAL SIMULATION OF TRANSONIC FLOW OVER SPACE VEHICLES

Natalia V. Palchekovskaya

Abstract

In this study peculiarities of transonic flow over a space vehicle similar to that of the ExoMars project are studied numerically. Dependencies of axial force coefficients on Mach number are obtained. Flow field transformation is shown when Mach number changes from subsonic to supersonic values. Critical Mach number, at which local supersonic zones disappear, is found.
