Abstract

A finite volume method is applied to calculate the steady free surface flow around a submerged hydrofoil moving at steady forward speed. The Reynolds equations are solved in a body fitted non-orthogonal H-type grid and the k-e model is adopted to simulate the turbulent stresses. The wave pattern above the body is calculated following an iterative Lagrangian procedure to satisfy both the kinematic and dynamic free-surface boundary conditions. The main objective of the work is to improve the convergence rate of this procedure. 1 Introduction The recent development of advanced computational methods that calculate the complete 3D free-surface flow past ship-like bodies, has provided very encouraging results at model scale, e.g. [
