The Use of Small Probe Volumes with Phase Doppler Interferometry
Abstract
Phase Doppler interferometry utilizing a probe volume much smaller than the droplets being measured has been shown to work well when coupled with a phase and intensity validation scheme which is capable of eliminating trajectory dependent scattering errors. Measurements in monodispersed droplet streams have been performed to characterize the probe volume, and an intensity validation scheme and corresponding probe volume correction factor have been developed. Volume flux measurements in dilute sprays have shown a significant improvement over standard phase Doppler interferometry techniques at small beam waist to droplet size ratios.
