FIG. 2.

Photographs of the cavitating line vortex cores for . The maximum distance between vortices is . The flow is from left to right. (a) On the right there is a view of the trailing edge of the two hydrofoils. The vortices orbit, and the circled area to 3 chord lengths downstream of the trailing edges marks where radially oriented secondary vorticity bridges are first observed. The overall field of view is . (b) An image centered on the circled area of (a) where the merger region and two vorticity bridges are evident. The field of view is .
