NUMERICAL IMPLEMENTAION OF A FREEZING-FRONT MODEL FOR WATER-SATURATED MEDIA THAT INCLUDES THE DEPENDENCE OF THE PHASE-TRANSITION TEMPERATURE ON THE PRESSURE AND CONCENTRATION B. N. Pavlov and E. E. Petrov UDC 532.546+519.63 A computational algorithm is constructed for solution of the problem of freezing of water-saturated porous media with account for the dependence of the temperature of the phase transition of pore moisture on the pressure and the concentration of a dissolved impurity. The mathematical model of the process considered is based on a generalized formulation of the well-known Stefan problem. Examples convey results of computation. JEPTER7492019998 JEPTER749208
