Turbulent-Eddies-Significance
Versuchsdesign aus angeströmten Zylinder und dahinter befindlichem fischähnlichen Körper in wirbeldominanter Strömung
Table of contents
Short description
The project investigates the stresses on fish caused by defined turbulent conditions and their ethohydraulic relevance, whereby turbulence is conceptualised as an eddy-dominated flow. For this purpose, numerical simulations in OpenFOAM and physical modelling are carried out to generate controlled vortex fields that interact with a rigid, fish-like body.
Central project goals are the calibration and validation of a 3D HN model as a digital twin, the analysis of vortex structures and their influence on fish, and the development of numerical methods for the evaluation of fish-relevant variables in the near field. Supplemented by laboratory tests (including artificial lateral line probe and timely resolved 3D-PIV) and a literature database, the project contributes to the well-founded ethohydraulic evaluation of fish in eddy-dominant flow.
