Fundamental research includes cavitation inception studies, super-cavitating and ventilated hydrofoil theory, hydroelastic phenomena, effect of cavitation on fluid transients, vortex cavitation, sheet/cloud cavitation, cavitation induced lift oscillations, effects on fluid transients cavitation erosion, and acoustics of bubbly flows, and many other related topics. As progress was made in computational fluid dynamics, the emphasis of this research has shifted from exclusively experimental and analytical studies to the use of an interactive experimental/numerical approach.

UMN supercavitation* model in the SAFL
high speed water tunnel.
*Supercavitation occurs when an underwater body is enveloped by a large, continuous vapor/gas cavity. It provides a means of significantly reducing the drag of an underwater vehicle, thus enabling a dramatic increase in maximum speed. |
