Title: DESIGN AND FABRICATION OF LOW SPEED WIND TUNNEL FOR AERODYNAMIC MODEL TEST
Abstract: In the current world of obtaining excellence with the maximum cost saving any and almost all the aerodynamic models are designed using CAD software; then tested for preliminary results. These designs however need to be verified and tested in real time which, given budget constraints cannot be done on a full scale. To obtain the aerodynamic properties and response of the plane under various conditions and orientations of different models, wind tunnels are used. Aircrafts, Automobile vehicles and other aerodynamic models like aerofoil etc. encounters different flow conditions. The complexity of flow involved while moving from a low subsonic regime to a supersonic regime are immense, including the crossing of sound barrier which offers immense amount of drag. Carrying out analysis of aerodynamic models in different tunnels increases the testing time and in some cases, requires modification of the model to be accommodated in three separate tunnels. Such a problem can be overcome by design of a Low cost, down sized wind tunnel which is capable of generating favorable testing conditions. The present study focus on design and fabrication of low wind tunnel for testing of various aerodynamic conditions of variety of models. Wind tunnel designed over here is of low speed and subsonic conditions. Various parameters are evaluated for aerofoil model tested in wind tunnel. The results obtained experimentally are in good agreement with theoretical results.
