As early as 1945, there was evidence that, in addition to the flow parameters normally considered to affect the cavitation performance of a pump, there existed a further influence derived from the thermodynamic properties of the fluid being pumped[1]. In the case of hot water, Stahl and Stepanoff[2] have shown a difference in performance from cold-water results with all other cavitation parameters being equal Similarly, Salemann[3] demonstrated a difference and effected a correlation between butane and water test results. In cryogenic liquids, Carter[4] has reported a small but definite effect for liquid oxygen and Caine et al.[5] have discussed thermodynamic effects in liquid hydrogen. Previously in an early report on pumping liquid hydrogen, Jacobs et al.[6] derived a “Cavitation Tendency” parameter based on thermodynamic properties, which predicted improved cavitation performance in liquid hydrogen.
