| 摘 要： | 依据实测的固液界面的运动规律和界面上的能量守恒。讨论了一种确定国管外凝国层界面上局部对流换热系数的方法。凝固实验中局部对流换热系数的推算表明：凝固时的局部对流换热系数不同于圆管外单相介质的稳定局部对流换热系数。

| Abstract: | ased on interface motion pattern and energy conservation, a new method is presented to determine local heat transfer caefficients at solid-liqwuid interface during solidification. It is shown that the local heat transfer caefficients during solidification are significantly different from local natutal convection heat transfer coefficients around a horizontal cylinder,. |

| Keywords: | solidification solid-liquid interface local heat transfer coefficient |
