Enlist the computer methods used which benefitted the airfoil performance along with wind- tunnel testing.(a) Panel method(b) Advanced viscous flow solutions(c) Panel method and advanced viscous flow solutions(d) Hit – and – trial methodsI got this question in semester exam.My query is from Modern Low Speed Airfoils topic in chapter Incompressible Flow over Airfoils of Aerodynamics

Answer»

The correct OPTION is (c) Panel method and advanced VISCOUS flow solutions

Best explanation: The numerical METHODS USED were like source and vortex panel methods and numerical predictions of the viscous flow behavior, to analyze skin friction and flow separation effects.This was followed by experimental testing for verification of computer RESULTS.
