Summary:Wind tunnels are used for the flow analysis over a flying object to be tested. Analyzing the flow plays a predominant role in aerodynamics study. The flow in the test section has to be uniformly streamlined and has to be parallel to the axis of the wind tunnel. The change in flow properties inside the tunnel with respect to the time should be negligible. So, before conducting a test process, calibration of wind tunnel has to be done. The desired outcome is obtained from the test only when the calibration is done properly. Hence proper care must be taken in doing it. Normally, calibration of subsonic wind tunnel is done by the Pitot static tube. It has the limitations of deprived accuracy and misalignment of probe with the flow direction. Therefore, new calibrating instruments are proposed by overcoming the limitations of Pitot static tube. In this paper, we discuss the two taping spherical flow analyser and the mirror edge flow analyser which are used for calibrating of wind tunnel.
