Abstract
In order to better study the internal flow characteristics of centrifugal pump as turbine, CFX software is employed to carry out numerical simulation
to obtain flow field under different working conditions for pump as turbine based on the standard
k - epsilon turbulence model and the SIMPLEC
algorithm. The efficiency curves of the pump and pump as turbine are obtained under different working conditions. The results show that the
effciency characteristics of the pump change greatly during the process of pumping. The efficiency of the turbine is higher than that of the pump
under the respective optimal operating conditions. The internal flow characteristics of a turbine change greatly with the change of flow. By analyzing
the related parameters in the internal flow structure, the internal characteristics of the turbine under different flow conditions are showed.
