| 摘 要： | 为了精确计算预测南水北调中线工程冬季输水的冰情,进而确保冬季干渠安全定时定量输水,对热量交换计算和冰盖表面温度两个方面进行了分析,提出了通过强迫边界条件法求冰盖的表面温度.通过模拟表明,准确的气象资料、准确的冰盖表面温度的计算对渠道冰盖厚度的变化过程极其重要,将对渠道冰期输水的控制运行研究有重要意义.

| Abstract: | In order to accurately predict the ice condition of the Middle Route of South to North Water Diversion Project in winter,to ensure the safety of the canal system and to make sure that enough water transfers from the upstream to the downstream in winter,a comprehensive analysis of the calculations of heat exchange and the temperature regime of an ice cover upper surface is made in this paper.Then a method called Forced Border Conditions is proposed to get the temperature regime of ice cover upper surface.A s... |
