Applications of Hydrofoils with Leading Edge Protuberances
Abstract
The leading edge modified hydrofoils generally create lift equal to or greater than their baseline counterparts at higher angles of attack (beyond the baseline stall angle) whereas at lower angles of attack the baseline models produce lift coefficients equal to or greater than the modified models. The drag coefficients of all modified hydrofoils are either equal to or greater than their baseline counterparts. The relative increase in drag associated with the leading edge protuberances, in turn, results in the lift-to-drag ratio for the modified hydrofoils to be less than or equal to the baseline models. The incipient cavitation numbers for leading edge modified hydrofoils were consistently greater than their their baseline counterparts.
