Abstract
The problem of a hydrofoil moving near an interface of two fluids of d ifferent densities is analyzed. An iteration scheme is proposed which imposes the boundary conditions on the body surface and on the interfa ce alternately. The numerical solution is obtained by using the linear ized theory and a Glauert-type expansion for the vortex distribution. Results are provided for various cases with different densities and di fferent speeds.
