POSSIBILITY OF DETONATION-WAVE PROPAGATION IN THE CHAPMAN-JOUGUET REGIME IN INHOMOGENEOUS-MEDIA

We consider detonation wave propagation in an inhomogeneous fuel gas m ixture at rest, whose initial state is characterized by values of pres sure and density that are, in the general case, functions of the spati al and time coordinates. The distance from the plane, axis, or center of symmetry can be used as the spatial coordinate. The sources of mass , pulse, and energy are assumed to be present behind the detonation.fr ont. The appropriate necessary conditions for the detonation wave to p ropagate in the Chapman-Jouguet regime are determined. The relations o btained are analyzed for some inhomogeneous media: media with variable density, media with heat release varying with distance, and media wit h burnout sources behind the detonation front.
