Studies on Jet Propagation

Objective

1. Measure velocity profile of a single jet at subsonic Mach numbers M=0.4,M=0.6,M=0.8 and supersonic Mach number M=1.5, along the centerline such that (x/d) varies from 0 to 30,applying increments of 1 mm on the traverse.
2. Compare the theoretical incompressible jet spread with measured spread rate.
3. Plot the velocity profiles and determine the difference in centerline velocity between the profiles at 10d and 20d
