The shape with negative pressure gradient (NPG) is the necessary condition that can ensure vehicle moving in water not to separate. Separation and cavitation characters of shape U-1 with NPG were simulated, and the results were compared with the Nesteruk's experimentation data. According to the potential theory, two different aerofoils with NPG were designed. Considering different angle of attack...
Analysis of internal flow in a Kaplan turbine runner with the Triangle Acute Clearance has been conducted in this paper. The flow fields at big opening conditions of the guide vane have been obtained by numerical simulations, with and without the consideration of the vane tip clearance and the runner blade triangle acute clearance near the hub. The analysis shows the following results: (1) At big...
