Turbulence Modeling and Detached Eddy Simulation with a High-Order Unstructured Discontinuous Galerkid method between the Unsteady Reynolds averaged Navier-Stokes approach and the Large Eddy Simulation. Some results, like flows over a flat plate and around a sphere, which could not be predicted with an Unsteady Reynolds averaged Navier-Stokes calculation, are calculated with high accuracy and compared with theory and experiments.

An Explicit Space-Time Discontinuous Galerkin Scheme with Local Time-Stepping for Unsteady Flowsand introducing local time-stepping and the shock capturing property, where we have adopted the artificial viscosity approach as described by Persson and Peraire to our STE-DG scheme. Thus, we try to resolve the shock within a few relatively large grid cells forming a narrow viscous profile by locally adding some amount of artificial viscosity.

Interfacial Area Transport Equation in Statistical-Eulerian-Eulerian Simulations of Multiphase Flow exemplary application, the development of a spray injection IATE is discussed. This includes interfacial growth due to velocity gradients and a new IA detection term which resolves ambiguities with boundary conditions.

Modelling and Validation of Covariance Transport Equations for Large-Eddy-Simulation of Ternary, Tur. This work develops and test transport equations for these moments, which include a non-equilibrium model for the subgrid scale scalar dissipation and the subgrad scale scalar cross-dissipation rates. Mixing models are then used to particle ensembles which represent the FDFs with the required moments.

Application of the Multi-Scale-Finite-Volume Method to the Simulation of Incompressible Flows with Ie formulation proposed by Peller et al. [5]. In particular we derive exact constraints for the pressure at immersed solid walls and show that the resulting Poisson equation is formally identical to the elliptic problems governing flows in porous media. An efficient iterative procedure for the comput
