Abstract A Wind tunnel is a mechanical assembly used to analyze the behavior of air flow and the effects they have over objects. Using a wind tunnel, one can control the stream conditions which influence forces on the test object. Through the calculations of the forces on the model, one can anticipate the forces on the full-scale test object. In the beginning, wind tunnels were used to utilized to comprehend and improve the execution of airplanes. Over the years, cars, bridges, and building were studied using wind tunnels.
