Outline of Final Research Achievements

A coupling system composed of the Reynolds Averaged Navier Stokes (RANS)-based CFD and non-linear FEM is proposed to establish an evaluation method on the performance of high-lift composite sails accounting for the elastic deformation of the soft sail. Besides, a three dimensional shape reproducing method by using the imagery analysis method is adopted in measuring the deformation of the soft sail, while it is validated by comparing with the wind-tunnel experiment with a scaled sail model. It turned out that the developed coupling system is able to estimate the hydrodynamic forces and the elastic deformation with a good accuracy. Further tasks regarding its application to the multi-sail are also turned out through the wind-tunnel test with a multi-sail model.
