nalysis Design and Optimization of Natural Flows

Analysis Design and Optimization of Navier-Stokes Flows

"A new tool to design highly efficient interacting sails by taking into account their real environment, viscous flow separations,..."



  • To increase propulsive force of interacting sails

  • To increase propulsive efficiency of interacting sails

  • To do robust multi-objectives optimization of trim and design of interacting sails and rigs

  • An Optimization plateform with a comprehensive interface, automated mesh generator, viscous flow solver, and personalized performance analysis

  • Project : a sail fitting module able to match any original sail design with a reduced number of parameters (based on sailcut)

  • A large panel of optimization algorithm (simplex, gradient, genetic algorithms, neural nets,...)









  • Exemple 1 : with ADONF we have optimized the design of a double rig to obtain a higher propulsive force (+50%) and fewer unsteadiness (-200%) with the same sail surface

  • Exemple 2 : with ADONF we have shown that a double rig is more robust to off-design trim for solo ocean racing
