| Abstract: | High-fidelity flow solvers and gradient-based optimisers are two major components of efficient aerofoil shape optimisation tools for solving multi-objective industrial problems. In such cases, complex flow phenomena are involved and the number of design variables is large. The paper presents a review of aerodynamic aerofoil optimisation activities applying high-fidelity gradient-based methods at Zurich University of Applied Sciences (ZHAW). Two optimisation chains have been applied in research projects with industrial partners in the fields of wind energy and aeronautical engineering. To validate the numerical results, 2D drag measurements were carried out by measuring accurate velocity profiles downstream of the wind tunnel models using Constant Temperature Anemometry (CTA). The test campaigns were carried out in different subsonic wind tunnels in Switzerland. For the sake of publishing the applications without showing confidential information, this paper undertakes case studies of independent benchmarking scenarios that address similar objectives and constraints. The paper gives a brief description of both optimisation chains, outlines the optimisation setups of the selected case studies, and includes thorough analyses and discussions of the numerical and experimental data. |
