atmospheric boundary layer simulation;  wind tunnel;  Data Processing

The data processing methods in wind tunnel simulation atmospheric boundary layer test are introduced from the aspects of average wind speed profile and turbulence structure, and the formulas of friction velocity u*, dynamic roughness height z0 and exponential α in the exponential law are given by curve fitting method, the calculation of turbulence integration scale and boundary layer simulation ratio are discussed, and how to judge the rationality of average wind speed profile simulation by the trend of V~LNZ curve and the dispersion degree of exponential α. The analysis results point out that due to the insufficient turbulence characteristic data, the turbulence characteristic parameters of the simulated flow field will deviate from some literature data, which cannot be said to be unreasonable.
