VISCOUS EFFECTS IN INCEPTION AND DEVELOPMENT OF CAVITATION ON AXI-SYMMETRIC BODIES. PART I. CAVITATION INCEPTION. PART II. A SEMI-EMPIRICAL METHOD TO PREDICT CAVITATION SEPARATION ON SMOOTH BODIES

The schlieren method was adapted as a flow visualization technique for use in water tunnels. The process of cavitation development on two axisymmetric bodies was studied using this approach and found to be greatly influenced by the presence of a previously unreported viscous laminar separation. Approximate computations of the position of transition on a body without laminar separation indicate that the incipient cavitation index is closely correlated with a negative value of the pressure coefficient at the predicted point of transition. Cavitation separation under fully developed conditions was investigated for viscous laminar boundary layer separation under fully wetted conditions. (Author Modified Abstract)
