Skin Friction over an airfoil
Hello Everyone, I am new to this forum. I was looking into skin friction coefficient issues. I am doing steady analysis of an airfoil using Transition SST model. I did meshing in ICEM with yplus less than 1. I am obtaining skin friction coefficient from plot-wall flux-skin friction coefficient. But the coefficient does not matches with the literature data. My lift and drag coefficients are in good match with experimental values.
Secondly, the export of skin friction data set is plotted with random lines in the graph. I do not know the issue.
What may be the issue with skin friction coefficient?. Am I plotting it the wright way? Kindly help accordingly. Thank you very much.
