Laboratory for Aeronautics at the University of Ljubljana used ANSYS software for the assessment of turbulence models and grid density on the pressure distribution of the modern upwind sails. Sail geometry and experimental results were provided by the Yacht and Superyacht Research Group (YSRG) of Newcastle University and the Yacht Research Unit (YRU) of the University of Auckland. Simulation data from ANSYS CFX formed basis for the research in drag reduction of Melges M24 racing yacht upwind sails. Using ANSYS ICEM CFD, the team generated high quality structured multi-block hexahedral grid. Several grids with different number of grid points were used to evaluate the grid independence. Assessment of turbulence models on each grid was optimized with ANSYS Workbench because of the interaction between grid parameters, ANSYS CFX solver and ANSYS CFD postprocessor, which allowed instant comparison of computed and experimental results. Simulation process with experimental data has enabled necessary information for simulation set-up for the research in mainsail drag reduction for MELGES M24 racing yachts. The reduced analysis cycle time allowed the team to study more design variables, which led to optimized design with maximum performance.
