A PROBLEM IN TURBULENT REACTING GAS DYNAMICS

Abstract

The case of a stream tube of cold gas going through a strong normal shock wave is treated. Chemical reaction is allowed to occur downstream of the shock, where the pressure and the distribution of certain turbulent correlation functions are prescribed as a function of distance. It is shown that the turbulence modifies the flow field mainly through the effects it has on the reaction rates leading to a hotter gas than if just the mean values of the thermodynamic functions for the turbulent flow were considered. The Gibbs' function for the fluid is also modified by the turbulent fluctuations, thus leading to different final equilibrium conditions.
