Abstract: This study presents diverse correlations used to predict Pumps-as-Turbines (PAT)-pumps operating point, based on results from direct mode of pump operation. In order to ascertain accuracy of correlations, flow in the pump is computed for direct (pump) and reverse (turbine) operating modes. Accuracy of computations is checked by comparing RANS (Reynolds-Averaged Navier-Stokes) results with experiments for direct mode. A new approach is proposed for PAT power plant design based on a  constant head, instead of traditional operation, in constant flow rate. A full PAT characteristic curve map can be obtained using numerical computation.
