12. Active Noise Control of Enclosed Sound Fields Optimising the Performance
Abstract : Active noise control is the art of reducing a primary unwanted sound field by interference with an actively created secondary sound field. To achieve high reduction, it is crucial to obtain both temporal and spatial matching between the primary and the secondary sound fields. READ MORE

13. 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

14. Numerical study on instability and interaction of wind turbine wakes
Abstract : Numerical simulations of the Navier-Stokes equations are conducted to achieve a better understanding of the behavior of wakes generated by the wind turbines. The simulations are performed by combining the in-house developed code EllipSys3D with the actuator line technique. READ MORE

15. Numerical computations of wind turbine wakes and wake interaction
Abstract : When wind turbines are placed in farms, wake effects reduce the overall power production. Also, turbine loads are significantly increased since turbulence levels are high within the wake flow. READ MORE
