Steady solutions to a set of two-phase reactive flow model equations are studied to test the hypothesis that observed deviations from Chapman-Jouguet (CJ) detonation states in porous solid propellants are manifestations of the two-phase nature of the flow. Shock jump relations are presented. A simple expression for a minimum detonation wave speed analogous to a CJ detonation for a single phase is given. The analogous CJ point is a sonic point. In the appropriate limit the minimum detonation velocity varies linearly with initial bulk density, and the corresponding detonation pressure varies with the square of initial bulk density. Non-ideal gas effects play an important role in determining CJ conditions. The effect of reaction zone structure is studied to determine its effect on detonation end states. 19 refs., 7 figs., 1 tab.
