Aerodynamics is the part of fluid mechanics that studies the motion of gases and the forces or reactions to which the bodies they interact with are subjected. Aerodynamics is not only important by itself but also as a complement to aeronautics. According to Mach number, or relative speed of a movable object with respect to air, these studies are divided into subsonic and supersonic aerodynamics, depending on whether that number is higher or lower than one.

Knowing the aerodynamics principles is useful for many activities, from the take-off and piloting of an airplane to driving a car or kicking a ball. Every time we move or throw an object, there are many physical principles acting, but we do not notice them.

Aerodynamic test tunnels are widely used to determine the actions of the wind on different types of bodies. The model under study remains motionless, whereas the flow medium is set in motion to generate the desired flow.

There are two types of wind tunnels: open and closed. In an open tunnel, the air enters the tunnel from the outside, and once it has passed through the tunnel, it returns to the outside. In a closed tunnel, the air is recycled cyclically, thus allowing the thermodynamic variables of the air to be controlled: density, temperature and pressure.

The Computer Controlled Closed Aerodynamic Tunnel, 2000 x 2000 mm, "TACL2000/2000C", is a wind tunnel designed to study subsonic aerodynamics in a tunnel in closed circuit and with incompressible subsonic flow.
