TO ANALYSE THESE PROFILES FOR THEIR PERFORMANCE AND EFFICIENCY USING FEM/CFD SOFTWARE.

TO RESEARCH THE MARKET FEASIBILITY OF THE PROJECT.3RECAPTULATIONDuring the minor project research, we have calculated the dimensions for an open circuit subsonic wind tunnel model to test a standard size automobile prototype.

The assumptions for the modelling are as follows: Maximum wind velocity at Test section is 50m/sFlow rate at wind tunnel is 180m3/sMaximum length of wind tunnel is 24m4Test Section
