Abstract
Unstable cavitating flow phenomena through three-blade cascade, which is similar to the rotating cavitation occurring in turbomachinery, are simulated numerically. A numerical method employing a locally homogeneous model of compressible gas-liquid two-phase medium is applied to solve above cavitating flowfields. Since the present method permits us to treat rather simply the whole flow fields inside and outside the cavity, it is possible to macroscopically analyze unsteady phenomenon with a long time evolution. From calculated results, we get a cavitation characteristics curve of the cascade, and discuss an aspect of propagation of uneven cavitation.
