What is Effect of the Air-to-liquid Mass Ratio on the Internal Flow and Near-field Spray Characteristics of a Two-phase Swirl Burst Injector about?

Previous studies have demonstrated that the two-phase swirl burst (SB) injector incurred ultra-fast and fine atomization, rather than a breaking jet core/film of conventional air-assisted atomizers. Thus, it has enabled clean, stable, and complete combustion of even highly viscous oils without fuel preheating nor hardware modification. The current study investigates the effect of the air-to-liquid mass ratio (ALR) on the internal bubbly flow formation that triggers the primary atomization by bubble bursting, and on the secondary atomization by shear layer instabilities. An SB atomizer with a diameter, D, of 1.5 mm, is investigated using high-spatial-resolution Shadowgraph and Particle Image Velocimetry. Results show that the bubbly flow commenced in the internal liquid tube at an ALR of 0.94 to initiate the SB atomization. The bubble zone elongated at higher ALRs and peaked at an ALR of 1.63. Further increase in ALR resulted in unstable sprays, indicating that 1.63 is the upper limit ALR for a stable water-spray of the current setup. An increase in ALR enhanced internal and external two-phase atomization, yielding finer droplets and decreased atomization completion length, which wa
