Measured Densities in UF6 Free Jets

  • P. A. Hoisington
  • S. S. Fisher


Measurements of gas densities in UF6 free jets expanding from converging nozzles into a vacuum are described. These densities are deduced from measured intensities of laser photons Rayleigh scattered by the gas. The nozzle Reynolds number Ren= ρoaodto, where dt is the nozzle throat diameter, ranges from ft. 1150 to 9200. Axial distances from the nozzle as large as 25 throat diameters and radial distances as large as 8 throat diameters are covered. Measured densities are in good agreement with those predicted on the basis of inviscid-flow method of characteristics calculations.
