Boundary Layers

The plate has two different surfaces so as to study the effect of surface conditions on the boundary layer. Side bodies can be used in the measuring section. The experimental unit used in the aerodynamics trainer allows the boundary layer on a flat plate to be studied. Thus the boundary layer phenomena can experience interference with a degressive or progressive pressure curve and, for example equalise the friction loss of the flow. For this purpose, air flows along the plate, parallel to the surface.
