An asymptotic model is derived for the nonsteady, nonplanar deflagration of energetic solids, such as nitramines, that experience exothermic reactions in liquid layers at their surfaces. The analysis takes into account the role of interphase heat transfer and the relative motion of gas and liquid in

In the first part of this paper a theory for isothermal homogeneous two-phase, liquid-gas flow in horizontal pipes is established by introducing the concept of Mach number and by considering the medium to be a pseudo gas. The theory takes account of wall friction, compressibility and flow choking. A
Homogeneous equilibrium two-phase flows are characterized by important variations of the local Mach number. Indeed, the sound speed can be several orders of magnitude higher in the liquid phase than in the two-phase mixture. For the simulation of such flows, a numerical method which can handle accur
