Since the overall efficiency of this machine is lower than conventional turbines, the use of these machines in large plants is not economically recommended. In this study, the effect of geometrical parameters of impeller on PAT performance is investigated. In the present research, the geometries of components of an available commercial pump were scanned and modeled. To make the study more feasible, Impeller was redesigned in CFturbo software. Commercial software of ANSYS CFX 15.0 was used to simulate the fluid flow within PAT. Numerical results are in good agreement with existing experimental data. Three main parameters, namely blade number variations, leading edge shapes and splitter blades were comprehensively investigated. Result shows that using 7 blades, rounding leading edge with suction side chamfer and 20% length s...
