Fluid-structure interactions of anisotropic thin composite materials for application to sail aerodynamics of a yacht in waves

Trimarchi, D., Turnock, S.R., Chapelle, D. and Taunton, D. (1970) Fluid-structure interactions of anisotropic thin composite materials for application to sail aerodynamics of a yacht in waves At 12th Numerical Towing Tank Symposium. 04 - 06 Oct 2009. 6 pp.

Record type: Conference or Workshop Item (Paper)


In recent years technological innovations has allowed large improvements to be made in sail design and construction. Sails and in particular kite-sails have application for sport, ships’ auxiliary propulsion and even power generation. Sails are divided into upwind and downwind sails (Fig.1), where upwind sails operate as lifting surfaces with small angles of attack whereas traditional downwind sails acted as drag device. New designs of downwind sails have reduced the area of separated flow and increased the lifting behaviour of the sails. In order to capture the lifting behaviour and regions of separation present in both types of sail careful application of computational fluid dynamic analysis tools are required. Solutions of the Reynolds averaged Navier- Stokes equations (RANSE) are often used as a part of the design process of high performance sailing yachts.The present paper discusses some initial investigations and future guidelines in order to get a more detailed description of the physics involved in sail FSI. Three main fields are therefore covered: the use of CFD in order to accurately capture flow features and a comparison with experimental results; structural modelling; and approach to coupling
