Aims

Discussion of topical challenges to modeling, simulation and optimization of complex and extreme fluids.

In many problems in the field of fluid mechanics, extreme conditions arise which cannot be handled appropriately by most analytical and numerical methods: For instance, the modeling of high fluid pressures in ball bearings or the consideration of different cell types in a blood stream in small vessels lead to complex fluid dynamical models of non-Newtonian type. This models contain strong nonlinearities and couplings of continuum mechanics to particle mechanics. Therefore, they constitute a big challenge for the numerics. Usual methods often can deal well with parts of the model. However, they are mostly not capable of solving the whole coupled problems. Algorithms for optimal control and parameter estimation often require high regularity and certain structural properties of the solution which are not given here. Further difficulties may arise due to complex geometries or moving interfaces.

This workshop brings together experts and junior scientist in the fields of modeling, simulation, and optimization of extreme fluids. Aim of the workshop is to leave established ways of thinking and to discuss approaches and possibilities especially for that regions where available methods come to their limits.

The workshop is supported by the “Mathematics Center Heidelberg” (MATCH) within the special semester on Fluid Structure Interaction. Furthermore, the “Heidelberg Graduate School of Mathematical and Computational Methods for the Sciences” (HGS) and the International Research Training Group 1754 “Optimization and Numerical Analysis for Partial Differential Equations with Nonsmooth Structures” (Munich - Graz) support the workshop.

Structure of the Symposium

The Symposium will take place at a small meeting center in the Old Town of Heidelberg, belonging to the University. The program of the Symposium will provide enough time for discussion and co-operation. Therefore the number and the time for lectures will be limited. There will be invited lectures and lectures selected from the offers of interested participants.

The website of the first symposium of this kind, which took place in autumn 2014, can be found here.
