DYNAMICS OF A "TWO-PHASE" BUBBLE IN COMPRESSION WAVES

The behavior of a vapor envelope around a heated solid particle in a variable pressure fi eld has been studied. Problems of this kind arise in propagation of shock waves in three-phase systems ″liquid–hot solid particles surrounded by vapor envelopes.″ The behavior of the system in the vicinity of the forward shock wave front on a linear rise in pressure in the system has been studied analytically. A simple formula describing the change in the radius of the vapor layer in time has been obtained.
