水库垂向1维水温冰盖耦合数学模型研究

寒冷地区水库冰盖的形成对水库大坝安全、电站运行、库区水温水质结构都存在重要影响。为了探讨冰盖对水库水温的影响,基于热力学理论建立了考虑冰盖生消过程的水库垂向1维水温数学模型,实现了对冰气热交换、冰水热交换和水体中的热量输运的精确模拟,得到了室内静水实验的验证。应用结果表明,模型能较好地模拟出水库冰盖的形成、发展和消融过...

Study on the Coupled Mathematical Model of the Vertical 1D Temperature and Ice Cover in the Reservoir

Ice cover formation of the reservoir in cold region has an important influence on power station operation, dam safety, water temperature and quality structure. Based on thermodynamics theory, the vertical 1D temperature Considering the process of ice cover growth and decay was established to investigate the influence of ice on temperature in the reservoir, . The heat transport simulation of heat exchange of ice and air, ice and water, heat Conduction in the water in this mathematical model was realized. And it was verified by laboratory experiment. Application results showed that this model can well simulate the process of ice cover growth and decay and the vertical water temperature.
