Ensemble light-scattering diagnostics were applied to an ambient pressure pulsed high-pressure spray. Measurements of the linear depolarization ratios showed that few spherical particles were present during the main injection event. The leading edge of the spray was found to be particularly poorly atomized. The power spectrum of the linear depolarization ratio and the intensity of scattered light were estimated. Estimates of the power spectral density show no distinct frequencies, implying that the droplet formation process can be modeled as a stochastic event.
