In this paper we are discussing about the low speed airflow tunnel. In which a low speed airflow tunnel was design and fabricated. The project covered the process of design and fabrication of the small airflow tunnel. In completing this project, a computer aided drawing (CAD) tool called CATIA V5 is used to design the airflow tunnel and aerofoil. The airflow tunnel is used in aerodynamic research to study the effects of air moving past to the solid objects. An airflow tunnel consists of a tubular passage with the object under test mounted in the test section. With the help of efficient fan system or by a blower we can make the air move past the artifact. In the testing we use the anemometer, manometer and solid artifact (NACA 23012 aerofoil). Experiments are conducted to find the lift and drag coefficient of NACA 23012 at different angle. An impression of fluid field flow around aerofoil is using smoke.
