SYSTEM CAVITATION PARAMETERS

Abstract

The use of Suction Specific Speed as a pump cavitation parameter will, in some cases, lead to inaccuracy and the incorrect interpretation of performance data. A new cavitation parameter, which is related to the Suction Specific Speed but avoids these disadvantages, is derived. This parameter, the Suction Index, can be employed as both a pump design and performance analysis parameter. In the area of pump design, t e use of the Suction Index in the optimization of a pumpfed liquid-engine missile system is illustrated. This parameter, when minimized in a pump design, minimizes the combined weight of the propellant tanks and pumps. (Author)
