Aerodynamic and Climatic Wind Tunnels in the FIAT Research Center

The Authors illustrate the Fiat wind tunnels (one aerodynamic and two climatic) for true scale vehicle testing and provide a detailed description of the relevant performance and fluid-dynamic characteristics.

All three tunnels are of closed-circuit, semi-open test section design, and are built of reinforced concrete (aerodynamic) and of sheet steel (climatic).

Also described is the fluid-dynamic investigation work on scaled-down wind tunnel pilot model as aid in optimizing airduct configuration and design.
