Characteristics of Hydrofoil Weirs
Journal of the Hydraulics Division, 1973The symmetric Joukowsky profile is investigated for its performance as a weir profile both under free flow and submerged flow conditions. The discharge coefficient is found to be a function of head and eccentricity factor, which defines the weir geometry. The discharge coefficient increases with profile thickness and crest curvature. The boundary layer

Journal of Navigation, 1967
Modern hydrofoil ships have evolved in response to the need for a fast reliable means of sea transportation which is capable of operating in all sea conditions. It is the purpose of this paper to describe how the application of modern stabilization and navigation technology to hydrofoil ships has contributed to the achievement of these goals. First,

Investigations on cavitating hydrofoils
1965Experimental and theoretical results are presented for the non-cavitating and cavitating performances of a plano-convex hydrofoil in both the isolated and cascade configurations. In the isolated hydrofoil tests special emphasis is placed on the unsteady region of cavitation separating the partially cavitating region from the fully cavitating region ...

Shape Optimization of Hydrofoils
2012In this thesis, a genetic algorithm: GA) is employed for shape optimization of hydrofoils for application in a sailing craft. The hydrofoil for a sailing craft should have high lift at lower speeds and low drag at higher speeds. Computations are performed for a hydrofoil in deep water as well as one close to the free surface. The commercially available
