(contribution withdrawn) Detached-Eddy Simulation of the MEXICO wind turbine with OpenFOAM — •Henry Plischka, Ivan Herraez, Bernhard Stoevesandt, and Joachim Peinke — ForWind - Center for Wind Energy Research, Institute of Physics, University of Oldenburg

A better understanding of wind turbines aerodynamics is necessary to increase the overall energy yield achieved by wind turbines.It also plays a crucial role in reducing the loads on the wind turbine blades and the whole structure. In this scope we conducted the present work which is a part of the project MexNext IEA Wind (Task 29). A very important part of this investigation is the analysis of the radial component of the velocity on the wind turbine blades. Indeed, it seems that this radial velocity yields to a vortex located at the middle of the blade. To gain a more detailed insight on the physics of such a secondary flow, a Detached Eddy Simulation (DES) was conducted with the open source CFD-software OpenFOAM. The simulations were validated with wind tunnel measurements of the MEXICO project and with CFD-simulations from other partner institutions of the MexNext project.
