supercavity closure

A summary of supercavity closure modes observed in SAFL experiments. Left: ventilated supercavity steady closure modes. From top to bottom: re-entrant jet (RJ), twin vortex (TV), quad vortex (QV), foamy cavity (FC); Middle: ventilated supercavity unsteady closure modes. From top to bottom: QVRJ hybrid, TVQV hybrid, TVRJ hybrid, interacting vortex mode, pulsating twin vortex (PTV); Right: natural supercavity closure, RJ with torodial vortices.

unsteady bfm

Ventilated supercavity in unsteady flow, backward facing model. Closure change and cavity surface instability can be observed.

unsteady ffm

Ventilated supercavity in unsteady flow, forward facing model. Closure change and cavity surface instability can be observed.
