Question:

Compare the surface pressure coefficient obtained with Dowell method using \(x_{0}=\mathrm{b}\) as expansion point and \(e_{0}=0.12\) and \(f_{0}=2.4 / b\) with the pressure coefficient obtained using Stahara-Spreiter method for the \(6 \%\) thick Guderly airfoil. Discuss the choice of \(x_{0}=b\).
