A generalized boundary condition potential flow calculation method has been combined with a momentum integral boundary layer method and a base flow theory of separation to predict airfoil viscous-inviscid interference up to and beyond stall. The resultant program considers laminar and turbulent separation and is, therefore, applicable to thin or thick airfoil stall. The calculated flow field includes the airfoil and the separation bubble recombination region behind the airfoil. Calculated pressure distributions and integrated values for lift are compared to measurements for several airfoils demonstrating different types of stall. The comparisons show a good prediction of the viscous interference effects.(Buehn)
