An investigation of unsteady 3D effects on trailing edge flaps
The present study investigates the impact of unsteady and viscous three-dimensional aerodynamic effects on a wind turbine blade with trailing edge flap by means of CFD. Harmonic oscillations are simulated on the DTU 10 MW rotor with a flap of 10% chord extent ranging from 70% to 80% blade radius. The deflection frequency is varied in the range between 1p and 6p. To quantify 3D effects, rotor si...
متن کاملComputational Investigation of Wings with Miniature Trailing Edge Control Surfaces
Miniature trailing edge effectors (MiTEs) are small flaps (typically 1% to 5% chord) actuated with deflection angles near 90 degrees. The small size, combined with little required power and good control authority enables the device to be used for both high bandwidth control and conventional attitude control. Numerous experiments and computational simulations have been conducted for two dimensio...
متن کاملEmpirical study of flat plate trailing edge flow and noise
This paper presents results of an empirical study on the flow and noise generated by the trailing edge of a flat plate encountering low turbulence fluid flow. Simultaneous measurements of flow and far-field noise data have been taken in an anechoic wind tunnel at the University of Adelaide. Velocity data about the trailing edge and in the wake have been measured using hot-wire anemometry. These...
متن کاملModel Predictive Control of Trailing Edge Flaps on a Wind Turbine Blade
Trailing Edge Flaps on wind turbine blades have been studied in order to achieve fatigue load reduction on the turbine components. We show in this paper how Model Predictive Control can be used to do frequency weighted control of the trailing edge flaps in order to reduce fatigue damage on the blade root. The design model is based on a modal model of the blade structure and a steady state aerod...
متن کاملComputation of trailing edge noise from an incompressible flow calculation
A new methodology for calculating low Mach number trailing edge noise is developed and tested. The input to this methodology is the fluctuating surface pressure obtained from an incompressible, turbulent flow calculation. The surface pressure is used to calculate an intermediate incident pressure. This pressure in conjunction with the sound-hard boundary condition yields the scattered pressure ...
