Before you begin, you may want to read the laboratory manual and then experiment manual.

The overall setup of the wind tunnel.  This experiment introduces the student to the use of Laser Doppler Velocimetry (LDV) as a means of measuring air flow velocities.

The section drag of a NACA 0012 airfoil can be determined from velocity measurements obtained in the airfoil wake.
   
The 0.5 m x 0.7 m wind tunnel has a maximum velocity of 20 m/s.
