You are required to advise on using a wind tunnel for testing a
scale model of a car for aerodynamic performance.
i. You have been given that the maximum velocity of the car is
140 km/h and the wind tunnel can handle air velocities up to 300
km/h. The car design team has a 1/4 scale model of the car for
testing. Determine whether the 1/4 model can be used for wind
tunnel testing.
ii. The wind tunnel has a test section that is twice as wide as
the car model. Comment on the appropriateness of this wind tunnel
for testing.
iii. Using an appropriate sketch explain where the centre of
gravity of a vehicle should lie in comparison to the centre of
pressure (consider side winds).
