Development of Computational Fluid-Structure Interaction Method for Yacht Sails

This paper presents a Fluid-Structure Interaction ( FSI) method for sails. In this FSI method the press ure field around the sail is determined using the Computational Fluid Dynamic s (CFD) package FINE/Marine using the ISIS solver. This computational method is based on the Reynolds-Avera ged Navier-Stokes Equations (RANSE). The computed p r ssure field serves as input for a basic structural model implem ented in the Nastran-based Finite Element Analyses (FEA) package Femap which determines the deformation of the sail ubject to the aerodynamic load. In an iterative pr ocedure the distribution of the surface pressure and the deform ation of the sail attain a stable equilibrium. The aim of the FSI method is to determine the steady flying shape of the sail an d to obtain the aerodynamic forces generated by the sail taking into account the deformation of the sail.
