Low speed windtunnel measurements on a two-dimensional flapped wing model using tunnel wall boundary layer control at the wing-wall junctions

An investigation on a two-dimensional wing model with a double-slotted trailing edge flap is described where tunnel wall boundeo'y layer control by blowing was applied to prevent premature flow separations at the junctions between the model and the tunnel walls. From the results it is concluded that tunnel wall boundary layer control at the wall...
