The schlieren method was adapted as a flow visualization technique for use in water tunnels. The process of cavitation development on two axi- symmetric 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.
