Introduction to the laboratories of the IfH and IWG
Civil Engineering students (B.Sc., 6th Sem) visit the laboratories of the institutes for Hydromechanics and Water and Water Development as part of the course „Wasserbauliches Versuchswesen“ (in German, Module Handbook Page 106)
Direct Numerical Simulation of the Formation of Subaqueous Sediment Patterns: Evolution Beyond the Initial Formation
This project has investigated the problem of sediment transport and subaqueous pattern formation by means of high-fidelity direct numerical simulations which resolve all the relevant scales of the flow and the sediment bed. In order to realistically capture the phenomenon, sufficiently large computational domains with up to several billion grid nodes are adopted, while the sediment bed is represented by up to a million mobile spherical particles. The study provides a unique set of spatially and temporally resolved information on the flow field and the motion of individual particles which make up the sediment bed, providing novel insight into the different mechanisms involved in the processes of sediment pattern formation.

Direct Numerical Simulation of Fully-Rough Open-Channel Flow Over Spherical Roughness Elements
Open channel flow can be considered as a convenient "laboratory" for investigating the physics of the flow in rivers. One open questions in this field is related to the influence of a rough boundary (i.e. the sediment bed) upon the hydraulic properties, which to date is still unsatisfactorily modelled by common engineering-type formulae. The present project aims to provide the basis for enhanced models by generating high-fidelity data of shallow flow over a bed roughened with spherical elements in the fully rough regime. In particular, the influence of the roughness Reynolds number and of the spatial roughness arrangement upon the turbulent channel flow structure is being studied.
