Flow Visualization of the Turbulent Jet at the Exit of a Single Element Nozzle by Holographic Technique, and Mean Velocity Profile Measurements with a Laser Doppler Anemometer
Abstract
The successful application of the holographic techniques for flow visualization is reported. the investigation was conducted on the turbulent jet at the exit of a single element oscillating jet nozzle. Both single and double exposure holographic interferograms were employed to determine for an unsteady (oscillating) turbulent jet, the jet structure, spreading rates and the flapping phenomenon. The structure of the steady jet was also investigated for comparison purposes. The mean velocity profile measurements of the oscillating and non- oscillating jet were also made with the help of a laser Doppler anemometer and results were compared with the theory and published results obtained by other methods.
