FINCL ACHIVES

Flow around a golf ball in water    

Cavity makes the flow visible: separation point, quasi-periodic pulsations and toroidal vortex in a wake region

Artificial Supercavitation

The process of supercavitating flow and the effect of the gravitational field: re-entrant jet inside the caivty and counter rotating twin-vortex.

Unsteady behavior of the partial cavity on a hydrofoil: 

Re-entrant jet flows disturb the sheet cavity and cause the cloud cavity to exfoliate periodically into the wake region. 

Bubbly flow on an inclined wall

Different bubbly flow regimes by air injection from a single and multiple holes in a free stream flow

Wake flow and cavitation

Lock-in vortex, streamwise and spanwise shedding vorticies

Tip vortex and cavitation

Typical patterns of tip vortex cavitation inception and growth 

Bubble cavitation on a hydrofoil: 

AoA = 3 deg, Cavitation No. = 1.00
