1. mesh quad+tri+3D extruded. at 17 grad most flow around airfoil is laminar



2. mesh only tri+3D extruded. at 15 grad flow behind foil is completely turbulent



so this pictures shows that we cannot get proper results for Cx, Cy due to bad prediction of the flow detachment.

try to find a solution, may be OF 2.1 will show better results
