非定常流体構造連成を考慮した流れ場の形状最適化

抄録

This paper presents numerical solution to a shape optimization of unsteady fluid-structure-interactive(FSI)fields. This paper formulates shape optimization for flow velocity control. Reshaping is carried out by the H¹ gradient method proposed as an approach to solving shape optimization. Numerical analysis program for the optimization problem is developed by using FreeFEM, and the validity of proposed method is confirmed by results of 2D problems.
