Automated process chains for optimal fluid dynamics design are gaining importance in automotive applications. So far, industrial implementations of optimal design processes in fluid dynamics are mostly restricted to shape optimization with bionic algorithms. However, on the basis of the recent progress in fluid dynamic topology optimization, as well as in industrial applications of adjoint-based shape design, we propose an adjoint-based design process chain comprising both topology and shape optimization. Starting from the available installation space, this approach delivers a tailored optimal geometry, making use of the whole potential of the available design space at each stage. The central element of this design process is the computation of sensitivity maps – for both topological and shape sensitivities. We present the theory underlying the computation of sensitivity maps via adjoint states, show sample maps for an air duct segment and a complete passenger car and point out the missing links of the proposed design process chain.
