Title: Validation of the 2D numerical invetigation methodology of the turbulent flow into an inducer with the 3D computation
Published In: Conference on Modelling Fluid Flow, The 14th International Conference on Fluid Flow Technologies, Budapesta, Ungaria
Description: The inducer is an axial impeller which is mounted on the same shaft with the impeller of a pump. Because it increases the pressure over the vaporising pressure, the inducer reduces the cavitation by producing a supplementary specific energy on the inlet of the impeller of the pump. The inducer is used for the pumps with severe suction condition and it has a “sacrificial role”. It will be replaced after a certain operating time and that is why the technology for its execution has to be simple and economical. The use of straight hydrofoil cascade for the construction of the blades of the inducer satisfies these requirements. The aim of this paper is to compare the results of the flow simulation obtained with 2D, which is used in the designing process, and 3D numerical investigation into an inducer. In order to validate the 2D and 3D numerical investigations of the flow, the distribution of the pressure coefficient for 3 sections of the blade (near the hub, middle and near the shroud) is compared with the experimental measurements of the pressure coefficient obtained from the investigations performed in a test rig upon the inducer.
