Design Comments and Experimental Results for Cavitation-Resistant Inducers up to 40,000 Suction Specific Speed

General geometric design considerations for cavitation resistant inducers are discussed, particularly those related to the “trial and error” type not covered by the textbook approach. A general correlation of four dimensionless cavitation parameters is developed. Experimental data for typical rocket engine pumps are given where suction specific speed values up to 40,000 are obtained. Finally, several schemes are given for augmenting the cavitation resistance.
