Unstructured h-adaptive finite volume schemes for compressible viscous fluid flow
The current thesis presents a novel methodology for solving the Euler and Reynolds-averaged Navier-Stokes equations for compressible fluid flow. The central objective of the presented research is to realize adaptively generated discretizations that are able to resolve the physically relevant …

High-order methods for convection dominated nonlinear problems using multilevel techniques
For industrial aerodynamic applications to compressible flow simulation, finite volume methods with low order of consistency are a mature technology, usually combined with shock capturing techniques. However, high accuracy is needed for those problems which involve a wide range of spatial and …

Adaptive timestepping for conservation laws via adjoint error representation
We study a recent timestep adaptation technique for hyperbolic conservation laws. The core of the method is a space-time splitting of adjoint error representations for target functionals due to Süli [47] and Hartmann [29]. It provides an efficient choice of timesteps for implicit computations of …

Iterative solvers in implicit time integration for compressible flows
Computational fluid dynamics (CFD) that was started in the 1960's is still an up-to-date research topic. In the Collaborative Research Center SFB~401 "Modulation of flow and fluid-structure interaction at airplane wings" being concerned with fundamental problems of high capacity aircrafts in …
