Interferometric Studies of the Flow in Fast-Expanding Nozzles,
Abstract
Interferometric studies have been performed in the test section of the Naval Ordnance Laboratory (NOL) 127 mm shock tunnel under conditions that closely simulate the flow in a gas dynamic laser (GDL) cavity. A Mach-Zehnder interferometer has been used to determine the density distribution in two nozzle configurations. In a two-dimensional fast-expanding nozzle, time-resolved interferograms were obtained at 200 microsecond intervals. For a multiple nozzle module interferograms were obtained in two mutually perpendicular directions. The experimental setup is described and the results are discussed. (Author)
