Subsonic wind tunnel theory
WebThe objective of this paper is to study the aerodynamic aspects of designing a subsonic Wind Tunnel and to study the existing aerofoil design to understand what parameters affect the lift and drag coefficients. The available literatures that deal with the design of wind tunnel or those components are illustrated firstly. WebIn addition, the student will become acquainted with the operation of a subsonic wind tunnel, including use of a Pitot-static probe and pressure transducer to measure wind speed.
