Aerodynamics and Aeroelastics

Topics: CFD simulation over complex terrains, Wind Farm Optimization, Simulation of individual wind turbines

 
Goals: 
  • Predicting the wind over complex terrains with Computational Fluid Dynamics using new algorithms, RANS approach with wall functions, and using new meshing strategies, e.g. unstructured grids
  • Optimizing the yield of wind farms taking into account the wakes by either proposing new wind farm layouts with different positions of wind turbines in the farm or by optimizing the wind farm control through the power setting of individual turbines for maximal wind farm production. 
  • Full 3D CFD simulations of individual wind turbines for prediction of power curve and optimization of blades for improved efficiency using RANS or LES modeling
 
CFD is used to predict the wind over complex terrains
 
Work together with Von Karman Institute
 
 
Wind Farm Optimization
 
Two optimizations are considered
Wind farm layout: positioning of wind turbines in the farm
Wind farm control: power setting of individual turbines for max wind farm production
 
Optimizations are based on
  • CFD simulations (COOLFluiD)
  • Wind turbines modeled using actuator disk
  • Neural networks
  • Genetic algorithms
  • Robust optimization using non-deterministic methods
