Velocity Measurements and Flow Visualization in Turbulent Three-Dimensional Supersonic Flows Using Oxygen Flow Tagging.
Abstract
An axisymmetric jet flow facility with a laser fluorescence flow visualization system has been developed. Advanced techniques in nonlinear optics and spectroscopy are being used to track oxygen molecules for velocity measurements. Similar techniques are being used to determine the distribution of energy states of oxygen molecules for temperature measurements. Density can also be measured by observing the direct light scattering from both oxygen and nitrogen. The great advantage of these techniques is they are non-obtrusive, instantaneous, two-dimensional and require no seeding of the flow with foreign material. Keywords: Flow visualization, Laser fluorescence.
