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? |
