摘　　要：针对沈家河水库宽深比较小,相关参数如流速、温度的变化水平横向比垂向变化小,建立垂向二维水流数学模型。在垂向做Δ变换,将变域变为规则区域。通过采用有限差分等方法对模型进行计算。并对模型通过实测数据进行了验证。计算结果表明,模型较好模拟了沈家河水库的二维水流的基本规律。Due to the width and depth of Shenjia River reservoir is small and the variation of relevant parameters such as flow velocity,temperature changes smaller in horizontal direction than in vertical direction,the vertical 2-D flow model is built.In its vertical direction,Δ coordinate transformation was made in order to change from variable domain to regular domain.Using Finite Difference Method calculates and measures data validates the model effectively.The result shows that the model is better to reflect the basic rules of the 2-D flow of ShenJia river.
