Hi all,

I am trying to validate experimental result with simulation for pressure distribution for NACA wing model. I used the formula in

https://turbmodels.larc.nasa.gov/lan...nter_4eqn.html

to find the value of F_length, Re_c.

Irrespective of my mesh, transition is predicted ahead of the experimental results-- meaning-- transition from numerical simulation is upstream and shorter in length compared to expeirmental work. I have used udf for different Re_th, Re_c and F_length but the result is same.

My Re is nearly 0.1 million and I am using normal C-type mesh for the analysis.
Any suggestions where I can get a course correction?
