A Review Paper on Design Development and Fabrication of Wind Tunnel

In the world, which is continuously progressing with the large amount of cost saving and where most of the aircrafts, automobiles are designed using software's and then they are analysed for preliminary results. In the real time designs however need to be verified and examined so that the budget constraint can be done on the appropriate scale. Wind Tunnels are used to get aerodynamic properties and response of the aircraft under different condition and orientation. It is a tubular like structure or apparatus with a varying cross-section area with air flowing in it. Wind Tunnels offer an efficient tool for finding the data that is associated with flow over scaled or full-scale model very fast. Therefore, we are going to see the fundamentals of the low speed wind tunnel design. The wind tunnel design in this case is capable of generating laminar flow. In test section, to analyse the internal flow manual analysis was used. This paper along with analysis focuses on different wind tunnel parameters like the shape of wind tunnel, size and orientation, air delivery, inlet outlet dimensions and length of the wind tunnel. Because of the ability of wind tunnel to combine quantitative as well as visualization data, it is a crucial instrument in designing and analysing any component that uses fluid dynamics.
