The new IIUM low speed tunnel is of a closed-loop type having a test section of 1.5m × 2.3m × 6m and a maximum speed of 50 m/s. This paper reports measurement results for initial calibration and flow characteristics of this newly constructed wind tunnel. The results show that the total pressure varies within 0.999≤Cpt≤1.003, the dynamic pressure varies from -0.5 to 0.4 percent from the plane mean value, the flow angularity holds within ±0.2º and the boundary layer thickness is less than 2 percent of the equivalent hydraulic diameter of the test section.
