Performance Augmentation with Vortex Generators: Design and Testing for Stall-Regulated AWT-26 Turbine

Performance Augmentation with Vortex Generators: Design and Testing for Stall-Regulated AWT-26 Turbine

Research output: Contribution to conference › Paper

Abstract

A study investigated the use of vortex generators (VGs) for performance augmentation of the stall-regulated AWT-26 wind turbine. Based on wind-tunnel results and analysis, a VG array was designed for and tested on the AWT-26 prototype, designated P1. Performance and loads data were measured for P1, both with and without VGs installed. The turbine performance with VGs met most of the designrequirements; power output was increased at moderate wind speeds with a minimal effect on peak power. However, VG drag penalties caused a loss in power output for low wind speeds, such that performance with VGs resulted in a net decrease in AEP for wind speed sites up to 8.5 m/s.
