Optimum Shapes of Supercavitating Hydrofoils at Zero Cavitation Number

Abstract

Abstract: We investigate the problem of the flow around a supercavitating hydrofoils at zero cavitation number. Making use of formulas for the lift and drag, derived in the work by D. V. Maklakov (J. Fluid Mech, 2011, vol. 687, pp. 360–375), we dtermine the hydrofoil shape that provides the minimum drag coefficient at a given lift coefficient. This ensures the maximum lift-to-drag ratio
