Project description
In this project, research groups of the University Heidelberg, Dortmund and Munich aim to develop efficient numerical methods to model, simulate and optimize multyphysik-problems in extreme conditions. A prototypical example occurs in ball bearings in satellites developed at Rockwell Collins Deutschland (RCD). Similar problems have to be analyzed in heat exchangers which are developed at the project partner P+Z Engineering for automobiles. In both examples models for thermal fluid-structure interaction have to be used. The regarded systems are very complex due to the coupling of several physical models on the one side and on the other side because of extreme parameters and nonlinear material laws. To extrude suitable parameters from experimental data a suitable parameter estimation problem has to be solved.

Key words
fluid-strukture interaction, optimal control, ball bearings
