چکیده انگلیسی
Turbulent wind data measured in the atmospheric surface layer and wind tunnels are used to estimate the Kolmogorov constant CkCk. The analysis discusses distinct procedures to obtain the mean energy dissipation rate and CkCk. We find that for our datasets the most reliable method is the third-order structure function one. The value found for the skewness of longitudinal velocity differences is in accordance with a multifractal approach recently proposed. Despite the limitations of the data discussed in the paper, the results point to a value of CkCk independent of the Reynolds number.
