Spray characterization using planar laser imagingResults on the application of a planar polarization ratio technique to spray and soot particle measurements are presented and compared with the phase Doppler particle analyzer (PDPA) measurements. With the assumption of a logarithmic normal distribution, reasonable agreement between the two techniques were obtained, demonstrating the capability of the planar polarization ratio technique to differentiate regions containing soot particles from those containing droplets. A comparison of quantitative measurement capabilities of the two techniques showed that the planar polarization ratio technique can be applied to complicated combustion environments for at least semiquantitative investigation of sprays.
