Platform for Multi-Model Design

This paper introduces a global platform for the simulation and the design of multi-model configurations. Fluid-structure interaction and optimization procedures are coupled with turbulent incompressible and compressible flow solvers in order to treat complex aerodynamics problems.First, the equations used in modeling the fluid and the structure are presented, as well as the numerics used in the solvers. Then follows the description of our optimization framework, the gradient approximation and several optimization methods we employed.The applications concern shape optimization for turbomachinery blades and aircraft airfoils and shape optimization coupled with aeroelasticity in aeronautics. The platform is dedicated to the treatment of realistic problems and serves as a powerful tool for design in industrial environments.
