Abstract
AbstractFlow measurement is an important parameter in the arena of Aerodynamics. In the techniques and methods available for flow measurement, wind tunnel test setup is the most appropriate tool. But the main problem faced while using wind tunnel is the existence of flow angularity in the test section. Determination of flow angularity is a crucial requirement for maintaining a laminar flow inside the test section. In order to figure out the flow angularity, calibration of the wind tunnel is a necessity. There are a wide range of instruments for the calibration of wind tunnel among which the Pitot static tube is the most commonly used one where accurate results are not expected. Hence, in the present work a new instrument is designed. The instrument consists of 15 holes distributed on 3 cobra shaped probe attached to a single wedge for the calibration of the subsonic wind tunnel which will provide grid wise results for the flow parameters.KeywordsWind tunnelAerodynamicsPitot tube
