Es wird ein nichtlineares Problem einer Gasströmung um einen spitzen Körper, bei der die Wärmestrahlung einen Einfluß hat, mit einer am Vorderteil vorhandenen Stoßwelle behandelt. Die Eigenschaften der Stoßwellen und des Strömungsfeldes hängen von drei wichtigen Parametern ab, nämlich vom Dickenparameter des Körpers, der Machzahl stromaufwärts und der Boltzmannschen Zahl. Die analytische Lösung für das Strömungsfeld wird bis zur zweiten Potenz des Dickenparameters abgeleitet. Die Form der Stoßwelle am Vorderteil wird hergeleitet. Die Ergebnisse zeigen, wie die Form der Stoßwelle durch das Verhältnis des Strahlungsverlusts zu einem typischen Körpermaß, der Boltzmannschen Zahl und der Machzahl stromaufwärts abhängt.

Shock Formation Distance in a Two‐Dimensional Steady Supersonic Flow Over a Concave Corner in Radiative Magnetogasdynamics

Using the theory for the propagation of wavefronts defined by weak discontinuities, the paper presents an analysis of shock wave formation in a two‐dimensional steady supersonic flow over a concave corner in radiative magnetogasdynamics. Transport equations are derived which lead to the determination of the shock formation distance and also to conditions which ensure that no shock will ever evolve on the wave front. It is assessed as to how the shock formation distance is influenced by (i) the presence of radiative and magnetohydrodynamic effects, (ii) the initial curvature of the concave wall, and (iii) the upstream flow Mach number.
