Abstract

The stability of alternate blade cavitation in flat plate cascades was examined by a linear analysis with a singularity method based on closed cavity model allowing the cavity length change. It was found that alternate blade cavitation was stable for the cascades with larger solidity and unstable for the cascades with smaller solidity. The equal length cavitation is stable only in the region of cavitation number larger than that where the alternate blade cavitation solution starts to separate from the equal length cavitation. This result suggests that the alternate blade cavitation could exist only for the cascades with higher solidity.
