| Abstract: | Based on the weakly compressible fluid,governing equations of the hydraulic transient process are established.One-dimensional and two-dimensional computational models of hydraulic transient process for water diversion system of hydropower plant are developed respectively.And then it is used to simulate the transient process of water diversion system,water level fluctuation,pressure distribution and velocity field in surge chamber.The results show that the computational results coincide with the experimental results and the error is less than 3%.Therefore,it can provide scientific basis for design of surge chamber. |
| Keywords: | hydraulic transient process weakly compressible fluid water diversion system surge chamber |
