Prandtl-Meyer expansion of chemically reacting gases in local chemical and thermodynamic equilibrium
Year: 1958
Abstract: It is found that Prandtl-Meyer flow, in which chemical reactions are occurring and are in equilibrium, can be simply and exactly calculated. The property of air which governs the flow is found to be a quantity which depends only on the ratio of enthalpy to the square of the speed of sound; the analogous quantity for an inert gas depends only on the ratio of specific heats. The maximum angle through which the flow may turn is generally larger when chemical reactions are occurring than it is in non-reacting air. A numerical example shows that the pressure variation with angle, as well as temperature and Mach number variations, may be considerably affected by the presence of the chemical reaction.
