heat stable

Instability of flow due to complex heat exchange and density variation leads to strong thermal convection in liquid region during the water solidification process. At the end of solidification process, intensity of flow decayed and the stable structure was rebuilt.

因为存在着复杂的热交换和密度变化，水在凝固过程中存在流动结构失稳，使得液相区内发生强烈的热对流.最后流动强度减弱，重新形成稳定结构。
