A Time-Accurate Inflow Coupling for Zonal LES
Marcel Blind, Johannes Kleinert, Andrea Beck +1
Generating turbulent inflow data is a challenging task in zonal Large Eddy Simulation (zLES) and often relies on predefined DNS data to generate synthetic turbulence with the corre…
Wake Tail Plane Interactions for a Tandem Wing Configuration in High-Speed Stall Conditions
Johannes Kleinert, Maximilian Ehrle, Andreas Waldmann +1
In this work, wake-tail plane interactions are investigated for a tandem wing configuration in buffet conditions using hybrid RANS/LES simulations with the Automated Zonal Detached…
Mach and Reynolds Number Effects on Transonic Buffet on the XRF-1 Transport Aircraft Wing at Flight Reynolds Number
Andreas Waldmann, Maximilian C. Ehrle, Johannes Kleinert +2
This work provides an overview of aerodynamic data acquired in the European Transonic Windtunnel using an XRF-1 transport aircraft configuration both at cruise conditions and at th…
Unsteady Navier-Stokes studies on loads, wake and dynamic stall characteristics of a two-bladed vertical axis wind turbine
Galih Bangga, Thorsten Lutz, Amgad Dessoky +1
Computational fluid dynamics (CFD) studies are carried out on a two-bladed vertical axis wind turbine (VAWT) operating at a wind speed of 8 m/s for the tip speed ratios () of 0.…
Numerical Investigation of Unsteady Aerodynamic Effects on Thick Flatback Airfoils
Galih Bangga, Thorsten Lutz, Ewald Krämer
The unsteady characteristics of the flow over thick flatback airfoils have been investigated by means of CFD calculations. Sandia airfoils which have 35% maximum thickness with thr…
An Examination of Rotational Effects on Large Wind Turbine Blades
Galih Bangga, Thorsten Lutz, Ewald Krämer
CFD studies have been performed to demonstrate the effects of rotation on large wind turbine blades. The 10 MW blade of the Advanced Aerodynamic Tools for Large Rotors (AVATAR) pro…
