Abstract

In this paper a new analytical relation is presented to approximate pressure-flow rate relationship in terms of the dimensions of impeller and channel geometries for small regenerative turbine pumps (RTPs) using some simplifying assumptions. Numerical simulation of the pump is conducted to compare the results with that of the analytical one. It is demonstrated that the presented analytical relation approximates the P-Q curve of the real pump satisfactorily. Finally, sources of the deviation of the pump behavior from predictions made by the proposed analytical relations are examined and discussed.
