Wake Characterization of a Multipurpose Scaled Wind　Turbine Model

摘要

The increasing need for validation of reduced-order wind-farm models over the last years requires even more sophisticated scaled wind turbines for wind tunnel testing. In this article, the wake behavior of the recently developed G06 scaled wind turbine model is presented. This model is designed for complex terrain experiments as well as wind farm control studies. Therefore, it combines compact design, realistic aerodynamic performance and sufficient instrumentation. The wake characteristics are studied in two different wind tunnels under similar inflow conditions with the results showing that the effect of the wind tunnel on the wake is negligible. Furthermore, wake measurements were made under two basic inflow conditions and they are evaluated in terms of velocity deficit, wake deflection and recovery rate. Results confirmed that all quantities are greatly affected by the inflow conditions.
