Vortex Pump as Turbine—A Type Turbine for Energy Generation or Recovery Based on Computational Fluid Dynamics Prediction

Journal of Fluids Engineering, 2019
An experimental vortex pump with a specific speed of 76 is investigated to get its performance and flow structure under noncavitation and cavitation conditions when the pump operates as turbine in the reverse direction by using computational fluid ...

Improvement of Hysteresis Characteristics of Francis Pump-Turbines When Operated as Turbine

Journal of Basic Engineering, 1972
The turbine hysteresis characteristics in Francis pump-turbines when operated as turbine were reported in the previous paper [1]. In the present report the characteristics of inner flow of runners will be observed and at the same time the effect given by the entrance angle of runner vanes and the sweepback at the entrance of runner vanes to the ...

PUMP AS TURBINE (PAT) IN INTERMITTENT DISTRIBUTION NETWORKS

2012
A hydraulic model was performed in order to evaluate potential energy recovery resulting by the use of centrifugal pump as turbines (PAT) in the water distribution network characterized by the presence of private tanks. The model integrates the Enhanced Global Gradient Algorithm (EGGA) (Todini [1], Giustolisi et al.

Experimental and Numerical Investigation of Centrifugal Pumps As Turbines

2018
Installation of Pumps As Turbines (PATs) in Water Distribution Networks (WDNs) is a relevant topic in the field of innovative management of WDNs. In case of excess head over a WDN, PATs can be used for both pressure regulation and hydropower generation.

Flow Configurations in Centrifugal Pumps Used as Turbines

1998
Direct and reverse operation of hydraulic machines can be interrelated by means of a theoretical expression that is instrumental in the prediction of the turbine H-Q values from pump performance curves. Tests have been carried out on four machine configurations in order to verify the validity of the procedure.
