Mie scattering imaging of a transverse, sonic jet in supersonic flow

The structure of a nonreacting transverse sonic jet in a supersonic primary stream was visualized by single-shot planar Mie scattering and conventional spark schlieren photography.

Description
Summary:The structure of a nonreacting transverse sonic jet in a supersonic primary stream was visualized by single-shot planar Mie scattering and conventional spark schlieren photography. Sites for Mie scattering were provided by the condensation of ethanol vapor premixed with the transverse jet injectant gas. The planar, time-resolved Mie scattering technique readily reveals large-scale turbulent structure in the transverse jet that cannot be resolved using the schlieren method. The structure appears to be characterized by regions of unmixed gas that penetrate well across the jet centerline. The observed structure persists far downstream (at least 25 orifice diameters) of the jet injector site. (Author)
