Karman-The Law of the Wall-Turbulence- Similarty Analysis

Bmalgil · December 11, 2020, 06:48

Dear All,

I have assigned a very simple task and failed, which is derivation of Karman law of the wall via similarity analysis.

I know prandtl, viscous sublayer, log-law, karman constant and integral and also the prandtl mixing length and the momentum transfer via reynolds stresses.

However, I couldn't derive "Karman Law of the Wall" via similarity.

Could you pls help me? or at least refer an online source that I can study what I didn't understand.

P.s. I even read "Turbulence and Skin Friction, v.Karman 1934 paper. Obviously, I'm doing something wrong very fundamental in terms of similarty analysis.

Any help is much appriciated.

Regarding to your question, since it's very broad. I am wondering which step in the derivation you are currently stuck on?
