LIQUID- AND VAPOR-PHASE DYNAMICS OF A SOLID-CONE PRESSURE SWIRL ATOMIZER
摘要
This article is aimed at providing detailed measurements of both the liquid and vapor phases in a simple evaporating isooctane spray from a pressure swirl atomizer. Discussion is provided regarding how well several nonintrusive techniques, including laser diffraction, phase Doppler, and infrared extinction, compare in determining both the liquid and vapor characteristics. Gas-phase measurements include axial and radial mean and RMS velocities. Liquid-phase measurements include drop size distribution, mean diameters, and the distribution of the liquid volume flux. In addition, measurements of the distribution of the vapor flux are presented. The phase Doppler system served as an independent comparison to the laser diffraction sizing results and the infrared extinction integrated vapor flow. Size comparisons are done on a spatially resolved and a line-of-sight basis. While the spatially resolved comparisons indicate similar trends, the deconvoluted laser diffraction results consistently predict SMDs approximately 10 μm larger than the phase Doppler results. The line-of-sight comparisons also indicate similar trends but deviate at the spray centerline and edge. Comparisons are made between the integrated fuel flow from the phase Doppler measurements and the integrated infrared extinction results.
