摘要：
The phase change in biological tissues during a freezing process is simulated by hyperbolic and parabolic heat equations with temperature-dependent enthalpy. It is observed that the experimental results are in a good agreement with that the calculated results by the enthalpy method. The results shown that the Fourier model predicts tissues temperature lower than of the non-Fourier model. Further decrease in freezing rate and freezing velocity is noticed with an increase in relaxation time value.
