THE DESIGN AND CALIBRATION OF A VERY LOW SPEED OPEN CIRCUIT WIND TUNNEL.

Abstract

To achieve very low velocities using the large pulley required closing the inlet vanes of the blower to a nearshut position. This caused a churning effect to take place in the blower housing, resulting in a pulse being set up in the tunnel. This pulse was the result of what might be called inlet air starvation and it caused the velocity variations mentioned above. Using the smaller pulley reduced the fan RPM and thus provided slower tunnel velocities at wider vane openings.
