Titel
Adjoint optimization of 2D-airfoils in incompressible flows
Abstract
Gradient-based optimization using the adjoint approach is a common method in shape optimization. Here, it is used to maximize the lift to drag ratio of a two- dimensional DU 91-W2-250 prole. The methods principle is explained as well as the implementation in the open source CFD code OpenFOAM. First, the optimization is done for different angles of attack without any constraints. Then, the cross-section area of the airfoil is held constant and also the effect of approximate gradients is shown.
