Baldacchino, D. (author)Vortex generators have become a ubiquitous sight on the modern wind turbine blade. These small, passive devices can increase the energy extraction potential of a rotor, but their subtle footprint disguises the technical difficulties associated with designing and integrating them onto wind turbine blades. The complexity of rotor inflow and the...doctoral thesis 2019

De Tavernier, D. (author), Baldacchino, D. (author), Ferreira, Carlos (author)To assess and optimize vortex generators (VGs) for flow separation control, the effect of these devices should be modelled in a cost and time efficient way. Therefore, it is of interest to extend integral boundary layer models to analyse the effect of VGs on airfoil performance. In this work, the turbulent boundary layer formulation is...journal article 2018

Nedumaran, A.K. (author)Vortex Generators (VGs) are flow control devices commonly applied in wind turbine blades, among other applications. A significant advance in the design of wind turbine blades would be the integration of vortex generators in the aerofoil optimisation process. Currently, aerofoil optimisation relies on either computational fluid dynamics or...master thesis 2016

Baldacchino, D. (author), Ragni, D. (author), Simao Ferreira, C.J. (author), Van Bussel, G.J.W. (author)In this work, the measured modulated integral boundary layer (IBL) characteristics of low-profile vortex generators (VGs) are used to validate new developments in a viscousinviscid interaction code which is modified to incorporate the effect of the passive mixing devices. The motivations are laid out and sample validation data is presented...conference paper 2015

Ye, B. (author)This project focuses on extending the existing model for two-dimensional laminar boundary layers to turbulent boundary layers and more importantly to include the modeling of transition to turbulence in unsteady boundary layers. The existing models are extended and a new transition model for unsteady boundary layers is developed. Successful...master thesis 2015

Seubers, Henk (author)This study is aimed at modelling of the unsteady interacting boundary layer around wind turbine rotor blades. It is shown that nonconservative mechanisms are present in this system, affecting the definition and approximation of solutions to the problem. The objective is to overcome the inconsistency of classical (dissipative) schemes, and find a...master thesis 2014

Özdemir, H. (author), Van den Boogaard, E.F. (author)In this study the two-dimensional, unsteady integral boundary layer equations are solved numerically together with a closure set for laminar and turbulent flows. A high-order discontinuous Galerkin method is used for the spatial discretization and a multi-stage Runge-Kutta scheme is employed for the time integration. Numerical results show good...conference paper 2011
