Wind tunnel testing is generally very expensive and time consuming. In addition, if the object to be tested (i.e. a car, an airplane) is too big to fit in the tunnel itself, a very accurate scale model must be produced, and Reynold's numbers (a number describing the flow conditions over the object) must be accurately matched to the expected operating conditions. These models can be prohibitively expensive as well.
A wind tunnel.
Unitary Plan Wind Tunnel was created in 1955.

Wind tunnels are different sizes.
It doesn't directly. A wind tunnel is used to detect the airflow over objects such as cars and planes to improve the streamlining.
Wind Tunnel with Dave Despain - 2003 was released on: USA: 21 February 2003
Frank wenham invented the first wind tunnel in 1871 in Greenwich England with his colleague John Browning

A wind tunnel is used to simulate air flow over a model of an airplane or a wing section so it can be studied. The model can be instrumented to measure the lift and drag and other parameters for study. The wind tunnel can produce air flow at the desired speed and condition. Engineers may use a wind tunnel to study and design a wing shape. The Wright Brothers developed the first wind tunnel to design the shape of the wing for their airplane. Wind tunnels can be used to study interference between parts of the aircraft or between an airplane and a bomb as it drops away. There are different types of wind tunnels: low speed wind tunnels, supersonic wind tunnels and hyper-sonic wind tunnels.
