Boundary Layers
1. Description
During incident flow of bodies fluids such as air “stick” to the
surface of the body and form the so-called boundary layer. The kind
of flow within the boundary layer – laminar or turbulent –
significantly affects the drag. The findings from studying the
boundary layer are taken into consideration when designing
aeroplanes, vessels and turbomachines.
The experimental unit – used in the aerodynamics trainer – allows
the boundary layer on a flat plate to be studied. For this purpose,
air flows along the plate, parallel to the surface. 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. 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.
A horizontally movable Pitot tube, adjusted using a micrometer
screw, measures the total pressures at various distances from the
plate surface. The plate can be moved vertically to enable the
recording of total pressures in the direction of flow. The velocity
can be determined from the pressures read off the tube manometers.
The experimental unit is attached to the trainer, simply and
precisely with quick release fasteners.
