A new optimal shape design procedure for inviscid and viscous turbulent flows. (English) Zbl 0892.76071
Summary: A new approach for optimal shape design is introduced. The main ingredients are an unstructured CAD-free framework for geometry deformation and automatic differentiation in reverse mode. Transonic inviscid and viscous turbulent flows are investigated. Both two- and three-dimensional configurations are considered. These cases involve up to several thousand control parameters.
