Book Description

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).

Book Description

Application of the method of characteristics to the linearized three-dimensional equation results in a relatively simple system of difference equations that can be used to compute the supersonic flow past boundaries for which no other linearized solutions are available.
