about the drag coefficient

I have a question about the drag coefficent of an airfoil. I use the RANS to compute the flow field of an airfoil,but I found the drag can't be well predicted. The drag induced by friction is very small compared with the drag induced by pressure even at the low attack angle. The drag coefficient is larger than the experimental data. Can anybody give me some suggestions? I'll appreciate any response! Thanks! Maximus
