Shape Optimization of Hydrofoils
<p>In 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 …
