Suction performance, pressure rise and efficiency for four different inducers are examined with CFD simulations and experiments performed with 18000rpm and 24000rpm. The studies originate from a research project which includes the design of a new test bench in order to judge the design of the different inducers. This test bench allows to perform experiments with a rotational speed of up to 40000rpm and high pressure ranges with water as working fluid. Experimental results are used to evaluate the accuracy of the simulations and to gain a be er understanding of the design parameter. The influence of increasing the rotating speed from 18000rpm to 24000rpm on the performance is also shown.
