CRITICAL FLOW IN A CHEMICALLY REACTING 2-PHASE MULTICOMPONENT MIXTURE

A model that describes the critical flow of chemically reacting, two-p hase, multicomponent mixtures in channels of constant cross section is discussed. As a consequence of an assumed interphase thermal and mech anical equilibrium the applicability of the model is restricted to sit uations where one phase is intimately mixed with the other, such that choking is determined by the sound speed in the homogeneous mixture. I t is shown that under certain conditions the highly non-linear tempera ture dependency of the reaction rate promotes the possibility of a mul tiplicity of steady state solutions to the problem.
