Abstract

At present, the domestic large-scale water conservancy projects increase in growing number augmenting the amount of the spillway tunnel with high head and big flow, and then the problem of the high speed air flow occur, which cause a series of issues. In order to carry out three-dimensional calculation of hydraulic characteristic of a certain spillway tunnel on the right band of a hydropower station in China, VOF model and turbulent model were used, and discharge capacity、water depth、 pressure distribution of pressure section、ventilation characteristics and wind speed distribution are given in this paper, which provide experience for optimizing shape of spillway tunnel. At the same time, a good agreement between numerical model results and test results is obtained.
