The cavitation problem is one of the most difficult to solve during development of high-speed centrifugal pumps, since pump cavitation performance decreases with increasing rotor rotation frequency. At the same time, lowering the frequency makes the hydraulic head of a centrifugal pump decrease. We suggest using a search method based on Sobol sequences to plot a compromise curve that would resolve the discrepancy between the cavitation performance and the hydraulic head of a centrifugal pump.
