    Abstract

    Calibration studies were conducted in the NAL 1.5mX 1.5m low speed wind tunnel to study the flow quality in the test section. The freestream velocity range was 10-13; 50m/sec. Measurements show that the wall static pressure is fairly uniform along the length of the test section. The mean velocity in the test section plane is uniform within +-0.3%. The longitudinal turbulence intensity is within 0.1% over the freestream velocity range of 10-40m/sec and increases to about 0.14% at 50m/sec. The13; transverse turbulence intensities are within 0.043%. The thickness of the boundary layer on the tunnel wall is around 7-Bcm in the freestream velocity range.
