Abstract

Heat transfer processes proceeding during the biological tissue freezing are discussed. The problem is described by the Dual-Phase Lag Equation (DPLE) supplemented by the appropriate boundary and initial conditions. The freezing models so far presented based on the well-known Pennes equation, but taking into account the physical properties of tissue the DPLE seems to be the better approximation of thermal processes taking place in the sub-domain of a frozen tissue. The characteristic feature of DPLE is the introduction of two lag times called the relaxation and thermalization times (τq and τT). The cryosurgery treatment using the spherical internal cryoprobe is considered. At the stage of numerical computations the explicit scheme of FDM for nonlinear problems is applied. The example of simulation is also presented.
