Cavitation in Water jet Pumps

Bulletin of JSME, 1979
Based on the similarity law of jet pump, a new cavitation parameter σ is proposed which has the similar meaning to Thoma's cavitation parameter in turbo pumps. The σ values are determined theoretically and presented as the function of specific speed nsj so that we may predict cavitation directly by using it in the designing. Experiments are carried out
