内融冰式蓄冰管融冰性能的数值模拟

摘要

Under the two circumstances with nature convection and without nature convection, a two-dimension heat transfer mathematical model for the internal-melt ice-on-tube with melting is established. Based on the model, the change trends of the outlet temperature, the heat exchange, the thickness of water are analyzed. Besides, the influences of nature convection of the water are considered. It provides theoretical instruction of optimizing system and matching parameters.%在考虑自然对流和不考虑自然对流两种情况下,建立了内融冰式蓄冰管融冰时的二维传热数学模型,分析了出口温度、换热量、融冰厚度等参数的变化趋势,并分析了融冰时自然对流的影响,为正确的进行系统优化、参数匹配等提供了理论指导.
