Simulation of Turbulent Flow With a CFD Method in a Power-Plant Containment

Principal Investigator: Eckart Laurien , Institute of Nuclear Technology and Energy Systems, University of Stuttgart (Germany)

HPC Platform used: Hermit of HLRS

Local Project ID: TurboCon

Two-phase flows with water droplets greatly affect the thermal-hydraulic behaviour in the containment of a Pressurized Water Reactor (PWR). In order to predict the local thermal-hydraulic behaviour in a real containment in the case of a severe accident, scientists of the University of Stuttgart generated a three-dimensional geometry of a model containment based on a German PWR.

Simulation of Unsteady Loads and Wakes of Wind Turbines at Turbulent Atmospheric Inflow Conditions

Principal Investigator: Thorsten Lutz , Institute of Aerodynamics and Gas Dynamics, University of Stuttgart (Germany)

HPC Platform used: Hermit and Hornet of HLRS

Local Project ID: WEAloads

In order to develop economic, efficient, and reliable wind turbines, the knowledge of the mechanisms that evoke transient aerodynamic loads effecting blades, tower, and the nacelle is essential. Using high performance computing technologies, researchers of the University of Stuttgart used high-fidelity Computational Fluid Dynamics (CFD) methods to accurately predict these unsteady loads. Particular interest was paid on the interaction of wind turbine and atmospheric boundary layer.
