According to Monin-Obukhov similarity theory, Reynolds-averaged surface layer winds can be expressed by $$\frac{\partial \bar{U}}{\partial z}=\frac{u_*\psi_M(\frac{z}{L})}{kz}$$ The potential temperature can be expressed as$$\frac{\partial…

I know that the von Kármán constant ($k\approx0.4$) is useful in turbulence modeling. Something that bothers me is my lack of understanding where $k$ comes from or the physical meaning behind it. If $k$ is mainly used as a proportionality in the…

I do not have a lot of knowledge in aerodynamics but I need to be able to derive turbulence strength (Cv2 and Ct2 - so called turbulence structural parameters I think) from turbulence intensity. Does anyone know how to do this?
