Heat transfer under conditions of phase transitions in bodies with anisotropic properties

An investigation is made of heat transfer in anisotropic bodies under conditions of phase transformations using the numerical solution of multidimensional unsteady-state problems of the Stefan type. A procedure of solving such problems is suggested. It is demonstrated that the characteristics of thermal conductivity tensors of both phases affect significantly both the temperature fields and the shape and velocity of motion of the boundary of phase transformations. Numerous results are analyzed of the effect which is made on the thermal state of anisotropic body by the orientation of principal axes and principal coefficients of thermal conductivity tensors of both phases.
