| 摘 要： | 本文在有相变的热传导方程中引入热焓,提出了一种稳定收敛迅速的数值方法——变时间步长焓法,用该方法分析求解了平板以及小球颗拉在气流中的凝固过程,计算结果与积分解的结果十分吻合。

| Abstract: | In this paper the enthalpy is introduced in the thermal conduction equation with phase change and a numerical method, enthalpy method with varied time step, which is more stable and easier to converge than others is proposed. The condensing processes for a flat plate and a small sphere in the flow have been solved by using the method, the results obtained are in good agreement with the integral solution. |
