Uncertainty Quantification for an Automatised RANS-Based Wind Resource Assessment Approach Open
In order to assess the model uncertainty of our RANS-based tool chain for wind-resource assessment “E-Wind”, we have simulated a large number of real wind farm projects with multiple measurement locations. Using one measurement location as…

Wind Turbine Loads in the Near Wake Open
This work is analyzing the the engineering wake models Frandsen and TNO for small inter-turbine distances. Therefore, loads generated by actuator line LES (AL-LES) wind fields will be compared with the loads generated by the mentioned engi…

E-Wind: Steady state CFD approach for stratified flows used for site assessment at Enercon Open
A new industrial methodology for CFD-based site assessment is presented. It is based on a steady state two equation RANS model and includes the effect of Coriolis force, forests and buoyancy in the equations for turbulence. The computation…
