Viscous-Inviscid Interaction

Airfoil Flow

Below are shown some results of a viscous-inviscid interaction tecnique for airfoil flows. The airfoil is the ONERA-A at Re = 2.8 million, and angles of attack indicated in the figures. The inviscidmodel was a first order doublet potential; the viscous model was the Navier-Stokes equations in vorticity- streamfunction.

Angle of attack = 10.3

Figure 1: = 10.3 deg.

Angle of attack = 12.3

Figure 2: = 12.3 deg.

Angle of attack = 13.3

Figure 3: = 13.3 deg.
