Abstract

This report presents the results of the calibration studies carried out in 0.2m Low Speed Wind tunnel. Measurements includes tunnel wall static pressures, free stream mean velocity and turbulence intensity profiles (in both X-Y and X-Z planes) across the tunnel for the velocity ranges of 10 to 20 m/s . A single component hotwire anemometer was used to carry out the mean and turbulence velocity in the test section and the wall static pressure were measured in a digital manometer (Furness). The mean velocity profiles show a good uniformity in the flow at the test section and the free stream turbulence levels are found to be in the range of 0.15 to 0.25 %. The boundary layer profile shows maximum thickness of about 10% of the tunnel width at 750mm from the test section entry.
