ABSTRACT
The phase change process in cryosurgery is simulated here with finite element scheme. The calculated results are consistent with experimental results. The compared results confirm the feasibility of the enthalpy model and finite element simulation method. And the successive Freeze-thawing Circle and multi-probe cryosurgery process are further simulated and the characteristic of the thermal field and thermal gradient around cryoprobe are analyzed. The application of enthalpy mathematical model and finite element scheme provide useful simulating means for the cryosurgery and will be beneficial for the progressing and extending of the cryosurgery technology.
