Abstract

The application of the boundary element method for numerical solution of the non-steady state problem in domain oriented in cylindrical co-ordinate system is presented. In particular, the thermal processes proceeding in biological tissue subjected to the action of a disk-shaped cryoprobe are analyzed. The problem is treated as the axially symmetrical one. The non-steady temperature field in domain considered is determined by nonlinear bio-heat transfer equation. The boundary condition on the contact surface between cryoprobe and tissue results from the temporary surface temperature (e.g. the constant cooling rate can be assumed). On the remaining parts of the boundary, the adiabatic condition can be accep
