Abstract

The unsteady cavitation characteristics of flat plate cascade were analyzed by a singularity method based on closed cavity model allowing the cavity length change. Through the formulation of present analysis, it was found that the unsteady cavitation characteristics are dependent on the cavitation number/incidence ratio as well as the steady cavity length. It was also found that the unsteady cavitation characteristics of cascades with solidity larger than 0.75-1.0 are very close to those of semi-infinite cascade. The present analysis can evaluate the cavitation characteristics of fiat plate cascades with various solidity, and can be easily extended to the analysis for cascades with blade thickness or camber.
