摘要
根据对某水库冬季气象资料的研究,建立了适用于水库冰盖内温度的数值模型并采用有限元方法求解,通过典型算例进行验证及误差分析,模拟结果显示了随着时间的变化冰冻期内部温度的变化规律,其结果符合实际情况。该模型易于编程实现,精度较高,可推广应用到其他水库的冰温计算场合。
Based on the meteorological data of a reservoir in winter,a numerical model for formation of ice cover in reservoir was established and the finite element method was proposed.Through the typical examples validate and error analysis,the simulation results demonstrated the regularity for change of the ice temperature by the time.The results were in agreement with actual situation,the calculation method with a good accuracy was easy to program and it could be used for other calculation in reservoir with ice cover.
