| Abstract: | On the base of studying of the feature of silt laden flow and the flowing characteristics in hydraulic machinery and from the view point of the basic conservation principles of mass and momentum, the model of two phase fluid is established and the governing equations of silt-laden water flow in hydraulic machinery is derived according to continuous medium theory of two phase flow and the analysis of interactional force acting between two phase, laying a foundation for flow field simulation. |
