山区水库的库区地形变化大、水文气象资料不足,对其水库水温进行准确预测的难度较大.结合老挝南俄河上的某山区水库,建立二维立面模型,基于FLUENT软件实现了水库水温预测,并对库区太阳短波辐射沿程分布及入流水温纵向分布等重要边界条件的取值方法进行了探讨.研究结果表明,库区太阳短波辐射可以按照沿程水面宽度与坝前水面宽度的比值进行折减取值;入流水温纵向分布可以采用分段函数,取值宜通过监测资料反馈分析确定.
Due to the large terrain change and lack of hydrological and meteorological data in the reservoir area of mountainous area, it is more difficult to accurately predict the reservoir water temperature.With a reservoir in a mountainous area on the southern Russian River of Laos, a two-dimensional façade model is established and based on FLUENT software, Prediction and the method of determining the critical boundary conditions such as the distribution of solar shortwave radiation in the reservoir area and the longitudinal distribution of inlet water temperature are discussed.The results show that the shortwave solar radiation in the reservoir area can be calculated according to the width of surface water and the width The value of the reduction value; longitudinal temperature distribution of inlet water can be used piecewise function, the value should be determined by the monitoring data feedback analysis.
