How wind tunnels work?

a wind tunnel works by turning on a gigantic fan in a round tunnel they place the car SUV etc. in the tunnel and turn the fan on to see if its aerodynamic since we cant see air they put a fog machine to make stream of fog to see the aerodynamics of the car the faster the fog passes the more aerodynamic it is


Who first used Wind Tunnel testing on automobiles?

Malcolm Sayer (For Jaguar) - He was an aircraft designer who moved to Jaguar and designed the iconic E type Jaguar. This was the first vehicle to be tested in a wind tunnel. With respect to the previous contributor, development of another "iconic" automobile, the SAAB 92, was underway more than a decade before Jaguar began development of the E-type. The SAAB 92, developed by aircraft engineers & designers, was one of the first (if not the first) moderately-priced, volume-produced car whose shape was perfected through wind tunnel testing. Its coefficient of drag in the low 0.30s backs up that claim.


What are disadvantages of wind tunnel testing?

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.

What should do if in a car in a tornado?

First of all you want to get out of the car and find a ditch because there is a risk of getting sucked up in the car. If you find a ditch it will protect from flying debris,never take shelter under an overpass as the shape accelerates the wind as it passes under the bridge, basically it acts like a giant wind tunnel

Are you at fault if the wind catches your door and hits another car?

Yes, of course! It's your car door that hit the other guy's car. You can't blame the wind. You should have been aware of the wind possibility and hekld onto the door, therefore you are to blame, even though you didn't do it on purpose. Just as you are to blame if you open your door and strike another vehicle, with or without wind.

Why do manufacturers use CAD in car manufacturing?

solid works (a cad) allows you to simulate a wind tunnel so car manufactures can see how fast there car go's and also solid works also allows you to calculate the amount of stress a material/product can hold
