摘要
Abstract
The characteristics of the diversion tunnel are distinguished from the conventional tailrace tunnel and the hydraulic phenomenons during the transition between the free surface and pressure flow in the tailrace tunnel rebuilt from diversion tunnel are much more complicat-ed,which include trapped air bubbles,air exhaust and suction. A numerical model was established to simulate the free surface-pressurized flow by using the slit method and the characteristic implicit method. Combining with a project example,the model was programmed and the comparison of results of the numerical calculation and the model tests show that the model is suitable for the kind of cases.关键词
