This question is addressed to this as well as the previous paper. I am very surprised by the rather poor agreement in the velocity profiles with the Baldwin-Lomax model, even in steady flow, especially because this model was optimized for such airfoil flows! Why is that so?

Discussions of the tunnel domain with and without Granville's pressure-gradient modifications of the Baldwin-Lomax turbulence model have been included in the paper. It is important to emphasize that Granville's change in the zero-gradient values of Ckleb and Ccp had larger influence in improving the solution than the pressure-gradient corrections to these coefficients.
