Abstract: Based on a numerical study of the potential flow through contractions of chosen geometry, Morel (1975) has given a method to obtain the shape of contraction which gives small adverse pressure ...

Abstract: A fully reversible axial flow pump‐turbine is a device that can work as a turbine and as a pump for both forward and reverse directions of flow. These machines find applications in tidal power plants. Double‐cambered ...

Abstract: The aerodynamic characteristics of an S-cambered profile are studied under forward and reversed flow conditions. The profile chord is cut by 3, 6, and 9 percent of the chord at the sharp ...
