Reynolds number has a direct impact on the performance of a wind turbine aerofoil. In this paper, the airfoil NREL S809 was chosen for the research, using numerical simulation and experiment for the performance of the two-dimensional aerodynamic airfoil flow. While Reynolds number varies from 1.5times104 to 2times105, both the drag coefficient and the lift coefficient have great changes. However,...
Reynolds number has a great impact on the performance of the scale model which is smaller than the original wind turbine. In this paper, three-dimensional numerical simulation by using the software FLUENT was applied to obtain the aerodynamic performances of the scale model. A prediction of Reynolds number impact on the scale model was presented and the results agreed well with the conclusion of a...
