Abstract

An experimental simulation method and device of turbulent wind based on active grid were developed. By adjusting the wind speed and grid motion parameters, the control of turbulent wind is realized. The effects of Rossby number Ro, grid Reynolds number Re_M, grid motion angular acceleration α and grid motion period length T on turbulence parameters were studied. The results show that the turbulence parameters are most sensitive to Rossby number. The average wind speed and turbulence intensity increase with the increase of Rossby number, while the turbulence integral scale decreases first and then increases. Based on the experimental parameters, the adjustable range of turbulence intensity is 5%-39%, and the adjustable range of turbulence integral scale is 0.15-1.56 m, which is suitable for wind turbine model experiments with a scale ratio of 1∶20-1∶1200.
