Airfoils in turbulent inflow
The project aimed at studying the effect of inflow turbulence in blade calculations by using CFD and with several Delayed Detached-Eddy simulations (DDES) for blade profiles, both profiles in free flow and in wind tunnel configurations.
Project description
By studying a profile section in a turbulent flow using computer simulations with Navier-Stokes models, the project will produce new knowledge about the impact turbulent inflow has on the aerodynamics of the rotor blades and thus create new methods for handling the turbulence in the inflowing air.
Results
To describe turbulence in inflows, the project developed two methods for turbulence generation. Methods were developed to add the turbulence generated at the domain inlet as well as inside the domain. The developed methods were used to compare results with measurements from the LM Wind Power wind tunnel for conventional low and high turbulence inflow alike. (Energy 10)
