The paper reports a numerical study of phase change heat transfer process in lung cancer undergoing cryosurgery. A two dimensional hyperbolic bio-heat model with non-ideal property of tissue, blood perfusion and metabolism is used to analyze the problem. The governing equations are solved by finite difference method based on enthalpy formulation. Effects of relaxation time of heat flux in hyperbolic model on freezing process have been examined. A comparative investigation of two different models (hyperbolic and parabolic bio-heat models) is also presented.
本文报道了肺癌冷冻手术中相变传热过程的数值研究。采用具有组织非理想特性、血液灌注和新陈代谢的二维双曲生物热模型来分析该问题。控制方程基于焓公式通过有限差分法求解。研究了双曲模型中热流松弛时间对冷冻过程的影响。还给出了两种不同模型（双曲和抛物生物热模型）的对比研究。
