Axisymmetric ventilated supercavitation: ventilation increases and cavitation index decreases from top to bottom.
A wedge-shaped fin partially piercing a supercavity. Note the partial cavity forming from the leading edge of the fin.
Comparison of phase locked photos of cavitation (left column) with numerical simulations of incondesable gas that come out of solution as a result of cavitation.
Cavitating (water vapor) vortices behind a cylinder mounted on the floor of the SAFL high speed water tunnel: speed is increasing and cavitation index is decreasing from top to bottom.
Closure of an artificially created cavity behind an axissymmetric disc. Top: Re-entrant jet method of closure where water can be seen slashing upstream into the cavity at the closure location. Middle: Twin-vortex method of closure. A vortex pair is observed at the closure location for the cavity. Bottom: Quad-vortex method of closure. Two pairs of vortices, situated one above the other, are observed at cavity closure location.
Artificial supercavitation in a periodic, unsteady gust.
Cavitation behind a NACA 0015 hydrofoil at angle of attack.
Ventilated cavitation behind a semi-axissymmetric disc with control fin. Note the necklace vortice upstream of the disc mounted in the floor of the SAFL Water tunnel.
