Abstract
Laminar boundary layer development downstream of a suction slot was
investigated in a low velocity wind tunnel. In order to observe the
effect of suction on the boundary layer, detailed boundary layer profiles
were measured at various stations upstream and downstream of a suction
slot for different suction flow rates. The investigation was carried out
for zero suction, 53.33 SCFH/ET. and 133.33 SCFH/JT. suction, by using
1/16 inch suction slot. The velocity profiles were plotted for 22 stations
with different suction flow rates with respect to the no suction flow case.
At the far upstream and downstream side of the slot, suction was ineffective
and velocity profiles had the Blasius velocity profile shape. Suction
had the maximum effectiveness a short distance in front of and downstream
of the slot. As the distance from the slot increased both upstream and
downstream, the velocity profiles tended to approach Blasius velocity
profiles asymptotically.
