The design of cavitating hydrofoils or wing sections is performed in a systematic fashion, by using a non-linear optimization technique. The cavity flow is treated with non-linear theory during the design process, with the effects of viscosity also included, in an iterative sense. Constraints are imposed in order to avoid non-physical solutions. The effects of three-dimensional flow are included in the case of elliptic planform wings, via the lifting line approach. Results are presented for different thickness forms in partial cavitation and for one camber form in super-cavitation, with or without the effects of the free surface included. Optimal solutions are given for a wide range of combinations of lift or cavitation number, in partially or super-cavitating flow, or in fully wetted flow. The regions in which a partially cavitating, a super-cavitating, or a fully wetted hydrofoil, is the most efficient solution, are finally presented.
