For performance optimization of combustion engines, in particular in the automobile industry, the optimal shape design of several components of the enigine, such as airducts, is crucial. In this context, for computer based rapid prototyping constrained free form shape optimization techniques are typically superior to parameterization based techniques due to their geometric flexibility. The associated numerical solution requires an efficient computation and yet accurate approximation of an adjoint-based shape gradient and also elements of higher order in a shape-gradient-related descent method for high Reynolds number flows. Moreover, geometric constraints need to be taken care of.

The PhD candidate shall develop a software tool for the numerical solution of this constrained shape optimization task. The work includes the implementation and analysis of a finite volume or finite element based optimization tool which involves a flow model, that is equipped with a proper turbulence model, and an associated adjoint scheme. The newly developed solver has to be tested for industry relevant use cases in a parallel computing environment. The PhD candidate will spend secondments for technical and scientific training at Math.Tec (Austria). The PhD degree will be awarded by Humboldt-Universität zu Berlin, Germany.
