Abstract
As the global demand for energy grows, numerous studies in the field of
energy efficiency are stimulated, and one of them is certainly the use of
pumps in turbine operating mode. In order to reduce time necessary to
determine pump characteristic in turbine operating mode problem was studied
by computational fluid dynamics approach. The paper describes various
problems faced during modeling (pump and turbine mode) and the approaches
used to resolve the problems. Since in the majority of applications, the
turbine is a pump running in reverse, many attempts have been made to predict
the turbine performance from the known pump performance, but only for best
efficiency point. This approach does not provide reliable data for the design
of the system with maximum energy efficiency and does not allow the
determination of the head for a wide range of flow rates. This paper presents
an example of centrifugal norm pump operating in both (pump and turbine)
regime and comparison of experimentally obtained results and computational
fluid dynamics simulations.
