Experimental evaluation of hydraulic design modifications of radial centrifugal pumps

Popis výsledku v původním jazyce

In the field of small hydropower, pump units in turbine mode (PAT) are frequently used as alternative to conventional turbines. In order to maximize their operation efficiency, it is possible to optimize the performances of these engines through various simple innovative modifications which relate mainly to the geometry of the flow parts. This paper deals with the results of several successful modifications verified on one such engine. While various simple modifications led to the increase of overall efficiency and power output by few percentages, power output increased by nearly 30 percent with the innovated runner blades geometry. The modifications also had positive effects on the pump operation, with significant increases in flow rate, head and total efficiency.
