Book Description
A shear layer formed by the merging of two different mass density and velocity, supersonic, inert gas streams (Ar and He) was investigated using both intrusive (probes) and non-intrusive (laser-based) techniques. Interpretations based upon mean pitot pressure surveys, namely shear layer growth rate and compressibility agree with established data. An aspirating probe in conjunction with a mass spectrometer comprised a gas sampling system for ultimately obtaining concentration profiles. Rapid scanning of such flows is possible with such a technique but additional efforts are required to make quantitative concentration assignments. The technique does, however, provide a means of qualitatively assessing mixing rates. Finally planar laser-induced fluorescence (PLIF) was used to establish spatially and temporally resolved images of the shear layer. Obtained images demonstrate the usefulness of PLIF to qualitatively monitor turbulent mixing phenomena in supersonic flows. 17 refs., 14 figs.
