Author: David Malcolm and Olamide Ajala-InyangPublication: Journal of PhysicsYear Published: 2024 Abstract. This paper describes a project for predicting and measuring the structural response of a 70 kW vertical axis wind turbine (VAWT), while offering insights for optimizing efficiency and ensuring longevity. We employ the traditional frequency response approach and model the turbine behavior using…
Author: Scott B. Capps, Alex Hall and Mimi HughesPublication: Wind Energy, John Wiley & Sons, Ltd.Year Published: 2011 Capps, Hall and Hughes evaluate how variation in wind turbine characteristics such as rotor diameter, rater power and hub height affect wind energy production in Southern California.
Author: Erik Mollerstrom, Fredric Ottermo, Anders Goude, Sandra Eriksson, Jonny Hylander, Hans BernhoffPublication: Wind EnergyYear Published: 2016 The relation between power performance and turbulence intensity for a VAWT H-rotor is studied using logged data from a 14 month (discontinuous) period with the H-rotor operating in wind speeds up to 9 m/s. The turbine, designed originally…
Author: Erik Mollerstrom, Fredric Ottermo, Anders Goude, Sandra Eriksson, Jonny HylanderPublication: J. Physics: Conference SeriesYear Published: 2019 The influence of turbulence intensity (TI) on the tip speed ratio for maximum power coefficient, here called λCp_max, is studied for a 200 kW VAWT H-rotor using logged data from a 14 month period with the H-rotor operating…
Author: Matthias Kinzel, Daniel Araya and John DabiriPublication: Physics of FluidsYear Published: 2015 Experimental results from three different full scale arrays of vertical-axis wind turbines (VAWTs) under natural wind conditions are presented. The wind velocities throughout the turbine arrays are measured using a portable meteorological tower with seven, vertically staggered, three-component ultrasonic anemometers. The power…
