In this study, unsteady cavitation and cavitation instabilities are numericaly analyzed around flate-plate cascade with slit in water/ air working fluid. In order to investigate the influence of location of slit between front and rear blades on cavitation characteristics, three kinds of two-stage cascade are arranged to have different length of front blade. Through comparisons with the results of previous study about cascade without slit, it is confirmed that cavitation instabilities are suppressed by slit effect in some cases without decline of cavitation performance of the cascade.
