Title: Unconventional Rotor Power Response to Yaw Error Variations

Abstract

Continued inquiry into rotor and blade aerodynamics remains crucial for achieving accurate, reliable prediction of wind turbine power performance under yawed conditions. To exploit key advantages conferred by controlled inflow conditions, we used EU-JOULE DATA Project and UAE Phase VI experimental data to characterize rotor power production under yawed conditions. Anomalies in rotor power variation with yaw error were observed, and the underlying fluid dynamic interactions were isolated. Unlike currently recognized influences caused by angled inflow and skewed wake, which may be considered potential flow interactions, these anomalies were linked to pronounced viscous and unsteady effects.

Wind Turbine Wake Measurements in the Operating Region of a Tail Vain

Conference Larwood, S

In conjunction with the National Renewable Energy Laboratory's (NREL's) Unsteady Aerodynamics Experiment (UAE) at NASA Ames, we measured the wake of an upwind 10-meter (m) diameter wind turbine in the typical region of a tail vane. The experiment was performed in a 24.4-by-36.6-m wind tunnel. We placed two sonic anemometers 0.58 rotor diameters downwind of the rotor at hub height. One was positioned nominally behind the nacelle at 9% radius and the second was placed 2-m outboard at 49% radius. The tunnel wind speed was varied from 5 to 25 meters per second (m/s) and the turbine rotor speed wasmore »« less

The Unsteady Aerodynamics Module For FAST8

Technical Report Damiani, Rick R. ; Hayman, Gregory

The new modularization framework of FAST v.8 (Jonkman 2013) was accompanied by a complete overhaul of the aerodynamics routines. AeroDyn is an aerodynamics module comprised of four submodels: rotor wake/induction, blade airfoil aerodynamics, tower influence on the blade nodes, and tower drag. Throughout the software overhaul, several improvements to the original theoretical treatments were achieved, including more accurate skewed-wake and unsteady airfoil aerodynamics, and the possibility of modeling highly flexible and curved blades. Under asymmetric conditions, such as wind shear, yawed, and tilted flow, the individual blade elements undergo variations in angle of attack that lead to unsteady aerodynamics phenomena,more »« less

Assessment of wind turbine component loads under yaw-offset conditions

Journal Article Damiani, Rick ; Dana, Scott ; Annoni, Jennifer ; ... - Wind Energy Science (Online)

Abstract. Renewed interest in yaw control for wind turbine and power plants for wake redirection and load mitigation demands a clear understanding of the effects of running with skewed inflow. In this paper, we investigate the physics of yawed operations, building up the complexity from a simplified analytical treatment to more complex aeroelastic simulations. Results in terms of damage equivalent loads (DELs) and extreme loads under misaligned conditions of operation are compared to data collected from an instrumented, utility-scale wind turbine. The analysis shows that multiple factors are responsible for the DELs of the various components and that airfoil aerodynamics,more »« less

Effects of inlet distortion on the flow field in a transonic compressor rotor

Journal Article Hah, C ; Rabe, D C ; Sullivan, T J ; ... - Journal of Turbomachinery

The effects of circumferential distortions in inlet total pressure on the flow field in a low-aspect-ratio, high-speed, high-pressure-ratio, transonic compressor rotor are investigated in this paper. The flow field was studied experimentally and numerically with and without inlet total pressure distortion. Total pressure distortion was created by screens mounted upstream from the rotor inlet. Circumferential distortions of eight periods per revolution were investigated at two different rotor speeds. The unsteady blade surface pressures were measured with miniature pressure transducers mounted in the blade. The flow fields with and without inlet total pressure distortion were analyzed numerically by solving steady andmore »« less
