26. Efficient Large-eddy Simulation for Wind Energy Applications
Abstract : Modelling the interaction of wind turbines with the ambient flow is essential for almost all technical aspects of wind energy exploitation. Large-eddy simulation (LES) is the most detailed approach feasible to model this complex interaction of wind turbines with the atmospheric boundary layer and the wakes of upstream turbines. READ MORE

27. Low-Rank Distributed Control with Application to Wind Energy
Abstract : This thesis addresses three different topics in wind power plant operation. Most of the research is focused on controlling a wind farm that is required to meet a power set-point. In this mode of operation, the wind turbines are able to vary their power production as long as the total power demand is met. READ MORE

28. The Lattice Boltzmann Method for Wind Farm Simulations: Validation and Application
Abstract : Many new challenges in wind energy require the use of large eddy simulation for accurate modeling of wind farm flows. However, the immense computational cost hinders its use in research and industry. READ MORE

29. Numerical studies of receptivity, stability and transition of wing and turbine blade boundary layers
Abstract : In the present thesis, receptivity, stability and laminar-turbulent transition of different boundary-layer flows are addressed and investigated by means of direct numerical simulations. In particular, flows over a wing and a low-pressure-turbine (LPT) blade have been the main focus. READ MORE

30. On stability of vortices and vorticity generated by actuator lines
Abstract : Vortices are present in nature and in many flows of industrial importance. The stability of configurations of vortices can have real-world consequences, because vortices play a crucial role in accelerated mixing. In particular, vortices are present in the wake of wind turbines and other rotors. READ MORE
