| Abstract: | The predictor-corrector time dicretization scheme is successfully introduced into the iteration solution program of phase change heat conduction via Enthalpy model, Therefore, the iteration number is greatly reced. Numerical examples are given which show good accuracy and high efficiency. Finally, a food freezing problem is calculated and the results are in agreement with those of experiments. |
