Abstract

The cavitations in turbo-machines decrease their efficiency and have a bad impact of their work-life and therefore constructors are always trying to avoid or minimize the cavitation risks in hydraulic machines. In this paper we have done the LDV measurement of flow in the model pump suction sump with baffle. In precedent works we did the PIV (Particles Image Velocimetry) measurement with and without baffle. Around the pump bell there are very complex vortices, which can affect seriously the flow characteristics of the pump. They can also cause vibrations, cavitations and decrease the efficiency of the system. In this experiment the pump suction sump and the pump bell with particular structure are used to search the flow situation in the surrounding of the bell. Both LDV and PIV experiments were done with steady flow using appropriate materials.
