Dynamics of Cavitating Cascades.

Abstract

A final report contains brief accounts of theoretical research on the unsteady cavitation characteristics of liquid rocket engine turbopumps. The objective is to produce estimates of the cavitation compliance and other unsteady characteristics which could then be used in analysis of the POGO instability. Blade cavitation is the particular phenomenon which is investigated, and linearized free streamline methods have been employed in both quasistatic and complete dynamic cascade analyses of the unsteady flow. Reasons for a discrepancy are discussed. The complete dynamic analysis presents a new problem in fundamental hydrodynamics. (Author Modified Abstract)
