Hi everyone,
In empirical correlation in gamma-Retheta, Equations 3.34
to 3.37 must be solved iteratively because the momentum thickness (θt) is present in the left hand side of the equation and also in the right hand side in the pressure gradient parameter (λθ) and For numerical robustness the acceleration parameters, the turbulence intensity and the empirical correlation should be limited as it was mention in thesis of Langtry. but I don't know In iteration for finding the momentum thickness when these parameter get values that are not fitted in the boundaries, what should I do?
