Wave Generated by the NACA4412 Hydrofoil near Free Surface
Journal of Applied Fluid Mechanics, 2013 The generation of wave due to moving hydrofoil in steady streams close to a free surface is presented. The potential-based boundary element method is employed to the NACA4412 hydrofoil with linearized dynamic and kinematic boundary conditions on the free

Limitations on 2D Super-cavitating Hydrofoil Performance
, 2007 Classical super-cavitating hydrofoil performance predictions have been based on linearised potential theory for zero cavitation number. More rationalised predictions of super-cavitating hydrofoil performance have been evaluated using a non-linear ...
