Hi there, thank you for using the forum, please check the following pages:
I usually use the tools you have mentioned, but bear in mind that those equations were developed for pipes. Thus, you may also use the reference length of your object in those equations (e.g., the chord of the airfoil). In internal engine applications we use the average piston speed and the cylinder bore as references.

\underline{\textbf{Introduction}}
Turbulent boundary conditions are often overlooked in simulation and left as default, which can lead to inaccurate results in many cases. Turbulent boundary conditions can be calculated using experimental results, but in most cases, it is enough to approximate them based on our understanding of flows and information about the domain to be simulated.
