Abstract

Abstract

A doublet integral equation was formulated for a two-dimensional dissipative potential flow around a hydrofoil submerged below the free-water surface. The free-water surface was assumed to involve energy dissipation and thus was source of damping. A doublet panel method was developed from incorporation of dissipative Green function approach and doublets distribution on the hydrofoil surface. Numerical computations were implemented and derived numerical results were in good agreement with analytic solutions and experimental measurements.
