An Experimental Technique for the Study of Velocity Profiles in a Laminar Jet Using a Pulsed Nitrogen Laser.
Abstract
This thesis investigated a nonintrusive technique for flow visualization of momentum jets. A flow system containing a fluid photosensitive to ultraviolet radiation (a solution of mineral spirits and photochromic dye) has been constructed for generating a momentum jet in a test chamber. An ultraviolet beam (337.1 nm) from a pulsed nitrogen gas laser was fired through the test chamber producing opaque traces in the jet and ambient fluid. Movement of the fluid deformed these traces and produced a record of fluid flow. Velocity distributions have been obtained in laminar jets. Keywords include: Laser velocimetry, Fluid velocity profiles, and Flow visualization.
