QUESTION 1 A 1/5 scale model of a race car is to be tested in a pressurised air wind tunnel. In order to ensure dynamical similarity between full scale and test, the Reynolds number and Mach number at test will be matched to the car at full scale. Calculate the freestream air pressure in the tunnel required to achieve dynamic similarity with the full scale car racing at standard atmospheric pressure of 1.013 bar. Provide your answer in units of bar to two significant figures. Assume that the air temperature T and speed of sound is the same at test and full scale, the air pressure p and density p follow the ideal gas law p/p = RT, where R is a constant, and the dynamic viscosity of air does not change with pressure.

At a sudden contraction in a pipe the diameter changes from D, to D2. The pressure drop, Ap, which develops across the con- traction is a function of D, and Dz, as well as the velocity, V, in the larger pipe, and the fluid density, p, and viscosity, u. Use D, V, and u as repeating variables to determine a suitable set of dimensionless parameters. Why would ti be incorrect to include the velocity in the smaller pipe a sa nadditional variable?

Wind tunnel test section km/h Model FD Moving belt Drag balance The aerodynamic drag of a new Volvo FH truck is to be predicted at a speed of 85 km/h at an air temperature of 25°C (p=1.184 kg/m³, u=1.849x10-5kg/m-s). Volvo engineers build a 1/2 scale model of the FH to test in a wind tunnel. The temperature of the wind tunnel is also 25°C. The drag force is measured with a drag balance, and the moving belt is used to simulate the moving ground. Determine how fast the engineers should run the wind tunnel to achieve similarity between the model and the prototype.
