Cavitating Flow over a Mini Hydrofoil

We consider a cavitating flow over a mini hydrofoil (foil profile: Clark-Y-11.7) having a 14mm chord length in a cavitation tunnel at various cavitation numbers. Experimental observations show that cavitating flows over a miniature hydrofoil display several types of cavitation behavior, such as cavi...

Summary:We consider a cavitating flow over a mini hydrofoil (foil profile: Clark-Y-11.7) having a 14mm chord length in a cavitation tunnel at various cavitation numbers. Experimental observations show that cavitating flows over a miniature hydrofoil display several types of cavitation behavior, such as cavitation inception, sheet cavitation, cloud cavitation and super cavitation with the decreasing cavitation number. Under the same cavitation conditions, cavitation over a mini hydrofoil would be suppressed in comparison to cavitation over an ordinary hydrofoil. This cavitation scale effect is suspected to be caused by the Reynolds number.
