    The effects impeller groove on the performance of regenerative type fuel pump were numerically studied by commercial CFD code(ANSYS CFX-10). To examine the effects of impeller groove, the shapes of the side channel and impeller groove were simplified. The blade angle(inlet/outlet), thickness of a vane and angle between inlet and outlet were selected as the main parameters for the impeller groove. The flow blockages between channel and impeller groove were caused by the thickness of the vane and shape of the groove. The internal flow characteristics of the new model were changed and its overall performance was improved than the existing model.
