Abstract

This experimental study was conducted in a wind tunnel using two turbines in tandem arrangement and downstream turbine is located at X/D=2. The purpose was to investigate how yawing the upstream turbine will affect the performance of the downstream turbine as well as the upstream turbine. Wind loading (thrust force), rotational frequency and power output are the parameters used to define the performance of the wind turbines used for the study. Besides, cobra probe (multi-hole pressure probe) was used to measure the flow field in the wake of the non-yawed (α=0°) and yawed (α=50°) upstream turbine. The effect of increasing the yaw angle of the upstream turbine on the overall efficiency of the wind farm (two model wind turbines) was also observed. Furthermore, overall efficiency was found to be strongly dependent on the incoming flow turbulence intensity level.
