冰球凝固过程的传热规律研究

On the heat transfer law in a solidification process of ice-balls

着重讨论冰球蓄冷系统在结冰过程中的传热规律。分析了冰球在凝固过程中的传热机理，建立了传热方程及相面能量方程，用摄动方法求得了方程的近似分析解。得到温度。

This articale studies the heat transfer law of iceing process in a ice-ball storage system. The heat transfer mechanism of ice balls is studied, their heat transfer and energy balance equations are set up. The approximate analytical solutions and the effective distribution of parameters respect to time are deduced with perturbation method.
