Summary

Experimental and analytical studies of the freezing/thawing process around a cryosurgical cylinder probe in a simulative biological tissue are presented in this paper. The enthalpy method and the finite element scheme are applied to solve the multidimensional phase change problems in cryosurgery. Very good agreement was found between the computed solutions and the experimental results. The influences of different cooling-warming schemes of the probe on ice ball development, temperature variation, axial and radial temperature gradients inside the tissues, and cooling requirement are analyzed.
