渦度最小化・最大化を目的とした非定常粘性流れ場の形状最適化

抄録

This paper presents numerical examples of shape optimization of unsteady viscous flow fields.We formlate shape optimization problem for vorticity minimization and maximization. Reshaping is carried out by the H¹ gradient method proposed as an approach to solving shape optimization. Numerical analysis program for the shape optimization is developed by using FreeFEM, and the validity of proposed method is confirmed by results of 2D problems.
