COMPUTATION OF BOUNDARY LAYER AND WAKE FLOWS AROUND IACC SAILING YACHT - FOR A CANOE BODY CASE

A numerical method is developed for calculating boundary layer and wake flows around the International America's Cup Class (IACC) sailing yacht for zero Froude number. The Reynolds-averaged Navier-Stokes and continuity equations are solved with the Baldwin- Lomax turbulence model, using a body conforming grid, finite-analytic discretization, and a PISO-type velocity-pressure coupling algorithm. The computational domain includes both port and starboard sides of the hull in order to account for the ship flow with yaw angle. An overview is given for the approach, and numerical results are presented and discussed for the canoe body of IACC sailing yacht for zero and non-zero yaw angles. Finally, some concluding remarks are made, including the requirements and prognosis for extension of the method for the complete hull geometry with keel and rudder.
