Various correlations were examined that have been used in |
|
the past for predicting mean droplet sizes generated by a |
|
single fluid jet. The correlation were compared with semi- |
|
quantitative data obtained from spark photographs and |
|
from a particle sizing interferometer. Jet properties |
|
were investigated for three types of fluids, i.e., water, |
|
Hexane, and a moderately energetic liquid monopropellant |
|
(LP) used in gun applications. The photographic data are |
|
only suitable for a semiquantiative analysis due to |
|
severe diffraction problems. Some preliminary low |
|
velocity droplet data were obtained with the particle |
|
sizing interferometer. The results strongly suggest that |
|
all correlations overestimate the droplet size and that |
|
the best agreement was obtained from a theoretical |
|
analysis by Mayer. Some additional studies were also |
|
performed on frictional heating and droplet scattering by |
|
an electric field. No evidence of ignition of the liquid |
|
monopropellant (LP) from frictional heating was found. |
|
Some evidence of droplet scattering by the electric field |
|
could be inferred from the photographs. |
