Dangi, Nirav (author)The wind turbine wake is a downstream region of kinetic energy and velocity deficit, higher turbulence and has a complex helical vortex structure. The wind turbine wake’s stability depends mainly on the ambient turbulence and the wind turbine tip- speed ratio. Researchers have developed several wake control techniques to mitigate this issue,...master thesis 2023

Saleem, Zohaib (author)Passive root flaps and in particular the Gurney flaps have been employed for improving aerodynamic characteristics for various applications since the 1970's. The effects of passive flaps on two dimensional airfoils have therefore been studied extensively, however, research on their application to Horizontal axis wind turbine blades (HAWT) is...master thesis 2019

Zhang, Xueqing (author), Sciacchitano, A. (author), Pröbsting, S. (author)Particle image velocimetry for the experimental assessment of trailing edge noise sources has become focus of research in recent years. The present study investigates the feasibility of the noise prediction for high-lift devices based on time-resolved particle image velocimetry (PIV). The model under investigation is a NACA 0015 airfoil with...journal article 2018

Zhang, Xueqing (author), Sciacchitano, A. (author), Pröbsting, S. (author)The present study investigates the feasibility of high-lift devices noise prediction based on measurements of time-resolved particle image velocimetry (TR-PIV). The model under investigation is a NACA 0015 airfoil with Gurney flap with height of 6% chord length. The velocity fields around and downstream the Gurney flap are measured by PIV and...conference paper 2016

Shah, J. (author)Aircraft noise has come under severe scrutiny due to growing number of airports and airline operations. The noise generated by high lift devices is now comparable to the turbofan engines due to increasing bypass ratios. A Gurney flap is a suitable starting point to study trailing edge flap aeroacoustics due to additional lift characteristics and...master thesis 2015
