Hybrid RANS/LES Study of the Development of an Airfoil-Generated Vortex

Reuß, Silvia and Probst, Axel and Knopp, Tobias and Wawrzinek, Katharina (2014) Hybrid RANS/LES Study of the Development of an Airfoil-Generated Vortex. International Symposium on Simulation of Wing and Nacelle Stall, Braunschweig, Germany, 01. Dec. 2014.

Full text not available from this repository.


In this work we investigate the requirements to simulate a generic, but still realistic lateral vortex that is generated by a flapping airfoil. Different modelling approaches, RANS and hybrid RANS/LES, as well as different strategies to design the grid are compared. The aim is to obtain a setup that allows a reasonable representation of the main vortex characteristics and to find a suitable strategy to model the generation and transport of the vortex within the framework of a scale resolving simulation. The results from the simulations are assessed using experimental data.
