Analysis 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
