• Research of the subgroup Theoretical and Computational Mechanics concentrates on fluid dynamics and transport phenomena. Emphasis is on better understanding complex flows by using computer simulation (CFD). Main topics are:

  - Development of efficient simulation methods for aero- and hydrodynamical applications. In particular we concentrate on direct numerical simulation (DNS) of turbulent flow. Analysis of the DNS results in terms of e.g. Reynolds stresses, coherent structures and bifurcation scenarios can be used to validate turbulence models in (industrial) large-eddy and Reynolds-averaged simulations.

  - Application of CFD techniques to support research by various groups from other disciplines, with emphasis on chemical process technology and bio-fluid dynamics. Long-term projects are running on flow and heat transport in extruders and static mixers, cochlear mechanics, arterial blood flow and liquid sloshing under micro-gravity.

• Research of the subgroup Numerical Mathematics concentrates on the development of numerical algorithms for the solution of partial differential equations. A substantial part of the research efforts is dedicated to supporting the CFD development in the group TCM. Main topics are:

  - Iterative solution methods for large sparse systems of equations, including eigenvalue problems, in relation to future computer architecture. These methods are based on newly developed preconditioning techniques which lead to (near) grid-independent convergence.

  - Discretization on highly nonuniform grids and near boundaries, and its influence on the subsequent solution of the resulting systems of equations.

  - Higher-order discretization and integration methods for long-time simulations.

  - Continuation methods for bifurcation analyses.
