Title:
CFD-based flow optimization for engineering and medical applications

Abstract:

The present talk discusses various optimization problems based on Computational Fluid Dynamics (CFD) simulations. The application of stochastic optimization methods, such as evolutionary algorithms, requires a large number of individual evaluations to explore the often high-dimensional design variable space. CFD simulations for engineering and medical applications are often unsteady and three-dimensional leading to large computational times. Specific examples, including geometrical optimization of wind turbines as well as flow-diverter stent optimization for the treatment of intracranial aneurysms considering the complex patient-specific geometry, involving enormous computational efforts will be presented during the talk.
