Abstract: Adding back vanes to the rear shroud of centrifugal pumps is sometimes practiced in order to alleviate large axial forces. Effective design and flow characteristics of back vanes remain obscure due to lack of knowledge ...

Abstract: Hydraulic losses of a low specific speed centrifugal pump originate in the friction and turbulent dissipations in all components between the suction and discharge nozzles as well as fluid recirculation mainly caused by ...

Abstract: In the current paper nondeterministic computational fluid dynamics (CFD) computations of three-dimensional (3D), developing, and statistically steady turbulent flow through an asymmetric diffuser with moderate adverse ...

Abstract: A common method to calculate the flow rate and consequently hydraulic efficiency in hydropower plants is the pressure-time method. In the present work, the pressure-time method is studied numerically by three-dimensional ...
