A novel idea: Calculating anisotropic turbulence only by Kolmogorov structure constant Cn2 and power law α

open access: yesResults in Physics, 2020
As stated in the present research, the anisotropic non-Kolmogorov turbulence model is more in line with the actual turbulence. However, anisotropic factor is vital for the accuracy of calculations, and measuring it precisely is a challenging task.
