Description:
Within the joint project ENVISON , the Center for Information Services and High Performance Computing (ZIH) and the Chair of Turbomachinery and Flight Propulsion (TFA) at the TUD University of Technology Dresden are making significant contributions to the development of models for the simulation of real film cooling holes and increasing the energy efficiency of the flow solver used.
The work covers the following main topics:
- Automation of the transfer of GOM scans into CFD meshes of real geometries
- Hybrid scale-resolving simulation of a turbine blade with real geometries of the film cooling and trailing edge slots
- Execution and analysis of high-resolution (wall-resolved) LES of real film cooling holes
- Derivation of an improved turbulence/heat transfer model for RANS simulations using the ML framework
- Increasing the energy efficiency of the flow solver by utilising accelerator cards
- Implementation of a consensus algorithm without global synchronization between coupled applications
