The reservoir seepage is closely related to the groundwater behavior. This paper analyses the following cases of groundwater condition commonly encountered in reservoir area: three conditions before storage, six conditions of borchole water situation during the drilling procedure, and four conditions after storage. It is seen that there would be no permanent reservoir seepage only when: (1)both the reservoir bank groundwater level and the deep piezometric water level are higher than the reservoir water level,...

The reservoir seepage is closely related to the groundwater behavior. This paper analyses the following cases of groundwater condition commonly encountered in reservoir area: three conditions before storage, six conditions of borchole water situation during the drilling procedure, and four conditions after storage. It is seen that there would be no permanent reservoir seepage only when: (1)both the reservoir bank groundwater level and the deep piezometric water level are higher than the reservoir water level, or(2) there exists a lagging zone of groundwater flow (if there is regional flow system). Otherwise, permanent seepage will happen.

水库渗漏与否与库区的地下水性状密切相关。本文主要分析了水库蓄水前常见的三种地下水条件、钻进过程中六种钻孔水位变化特征以及水库蓄水后常见的四种地下水条件。据此认为,在蓄水条件下,只有当库岸中的地下水位及深部测压水位均高于库水位或库区存在着地下水流停滞带时(当存在区域流系统时),水库才不致引起永久性的渗漏。否则,永久性的渗漏就会发生。

In this paper, the performarce of flow resistarce and heat transfer in the hydraulical and thermal entrance region of the single spirally Corrugated tubes is determined by experiments. The mean frictional cocfficient and Nusselt Number dimensionless equations involving x/D ratio of this tube are obtained by regression analysis. These equations provide basis for the designing of the short tube exchanger. The hydraulical and thermal entrance regions of the fluid air in the above-mentioned tube are presented. The...

In this paper the finite element method is employed to solve the streamfunction vorticity formula for viscous incompressible fluid flowing past two dimensional backward facing step. The vorticity on the solid wall are determined by the method of time iteration, without using the first order or second order accuracy of wall vorticity formula. We calculated the values of streamfunction and vorticity on the domain at Re=200, 400, 800 and 1000, and we compare our results at Re=800 with others, it is very agreement...

The effect of output boundary conditions on the computing results is also studied. The method used here is valuable to analyze the flow at the port of hydraulic valves.

对不可压缩流体沿二维后台阶流动的N-S方程的流函数-涡量式用有限元方法加以求解,固壁上的涡量用时间迭代法加以确定。分别计算Re=200,400,800和1000时流动区域的流函数和涡量值,并在Re=800时与有关文献的结果相比较,基本吻合。且在此基础上讨论了出口条件对计算结果的影响。本文的方法对分析流经液压阀口等流动问题具有借鉴意义。
