Wind Gust Generation for Wind Turbine Testing via Numerical Methods

The modelling of gust generation by an array of oscillating vanes at Delft's University of Technology Open Jet Facility is proposed. Focus is placed on identifying relevant in-field gusts that horizontal axis wind turbines are exposed to and reproduction via numerical methods in the wind tunnel setting. A computationally efficient model is...

Assessment of a State-Space Free Wake for Rotorcraft Flight Mechanics Applications

Interest on rotor wake analysis has always been a point of focus of rotorcraft analysis and design, its importance is undeniable and has been kept in current status within the research community as improvement of knowledge and tools have allowed the exploration of such phenomenon and its influence on engineering applications.

Computation of Rotorcraft Wake Geometry using NURBS

This thesis contains the results of research in the area of rotorcraft aerodynamics with a focus on method development related to the vortical wake generated by rotor blades. It is applied to a vortex tube representation of the wake (using a single NURBS surface) and a simplified filament wake model where only the tip vortices are taken into...
