Abstract
Rotating cavitation is an important problem, which makes it difficult to design reliable rotating machines. In the present study, a simple analysis method that tried to evaluate the cavitation instabilities of a rotating machinery by using one-dimensional system analysis software was attempted. In this method, cavitation compliance and mass flow gain factor are distributed in each flow path of the inducer. Analysis results show that cavitation instabilities, including rotating phenomena, exist. With the evolved analysis model, effects of various parameters on the eigenvalues of the system were investigated. Analysis results agreed with inducer test results qualitatively. Furthermore, by the analysis considered whirl motion of the rotor, effects of it on cavitation instabilities were investigated.
