Visualization of a Supersonic Underexpanded Jet by Planar Rayleigh Scattering. (Reannouncement with New Availability Information).

摘要

A Supersonic underexpanded air jet has been visualized by Planar Rayleigh scattering. The Mach disk, barrel shock and triple point are clearly visible, along with the turbulent shear layer downstream of the triple point. The High Spatial resolution obtained using Rayleigh Scattering from a laser sheet uncovers structures that are unable to be seen in line of sight measurements....
