I am pleased to invite you to my presentation that I held at the 5th Wind & Drivetrain Conference on April 6, 2022.

My name is Benedikt Michels, and I work at the German Aerospace Center (DLR). I joined the DLR Institute for Flight Systems in 2016 as a research assistant, after having obtained a Bachelor's degree in Mechanical Engineering and a Master's degree in Aerospace Engineering from the Technical University Braunschweig.

I have since been working on downwash models in the wind energy and helicopter research field and the VAST (and predecessor tools) development in general. Since 2022, I lead the DLR-internal project "LAISA" (https://dlr.de/ft/laisa), which aims to develop more holistic simulation capabilities for wind farm aerodynamics and aeroacoustics on the one hand, and a more integrated design process for load adaptive rotor blades on the other hand.

Abstract:

The presentation gives an overview of the emerging wind turbine simulation capabilities at the Institute of Flight Systems of the German Aerospace Center (DLR), using Simpack in combination with the in-house aeromechanics code VAST (versatile aeromechanics simulation tool).
Current activities focus on verification and validation, using a model of the 2.3 MW NM80 turbine from the DAN-AERO experiment.
The Simpack model of the turbine is set up by the DLR Institute of Aeroelasticity, using a python-written converter for the transfer of HAWC2-format input data into Simpack models.

The already available VAST extensions for wind turbine simulations include a BEMT and a free vortex-wake inflow model, both in combination with lookup table airfoils. Furthermore, a geometry model allows for freely configurable blade shapes. Other wind turbine-specific models cover the tower dam effect and wind fields. The coupling of VAST to Simpack via user-routine had already been developed in a previous joint project between DLR-FT and Dassault Systèmes (VaMeSH).
Initial simulations comparing the results with AeroDyn reference calculations have been carried out, showing very good agreement.
