Abstract

The boundary element method is applied to the numerical simulation of the freezing process proceeding in biological tissues under the influence of cryoprobe action. From the mathematical point of view the process discussed belongs to the group of moving boundaries problems for which the mushy zone sub-region (intermediate phase) must be considered. In this paper the mathematical model of the process is formulated using the fixed domain approach '^ and the evolution of latent heat is taken into account in a parameter called the substitute thermal capacity *• \ The generalized variant of the alternating phase truncation method *• * has been applied and the basic mathema
