Breakup processes of liquid jets in subsonic crossflows

Experimental investigation on the effect of liquid injection by multiple orifices in the formation of droplets in a Venturi scrubber

“…Some research studies about the process of atomization also take into account its application in combustion devices. Wu et al [15] carried out a study of the rupture of a liquid jet transversal to air stream with injection from a flat orifice. The authors divided the region of rupture into: a column region with large droplets and a spray region.…”

Breakup modeling of a liquid jet in cross flow

“…They categorized the breakup regime into different transitions considering more detailed deformation, i.e., nonoscillatory and oscillatory deformations, bag breakup, multimode breakup, shear breakup, and catastrophic breakup. Chen et al (1993) and Wu et al (1997) characterized the near-field jet breakup process as three different regimes: liquid column, ligament, and droplet regimes. Ranger and Nicholls (1969) may have been the first to use the characteristic breakup time to demonstrate the effects of the high free-stream velocity (M s =1.5~3.5) on drop deformation, displacement, and breakup time, i.e., the time for the complete breakup process.…”

“…The overall breakup process including deformation, liquid *Corresponding author. e-mail: mschon@cjnu.ac.kr fragmentation, and completing disintegration is mostly dictated by two independent nondimensional numbers: the Weber number and the Ohnesorge number, in conjunction with the characteristic breakup time (Pilch and Erdman, 1987;Hsiang and Faeth, 1992;Chen et al, 1993;Wu et al, 1997).…”

Performance estimation of a Venturi scrubber using a computational model for capturing dust particles with liquid spray

“…Droplets are stripped from the column by surface breakup. The liquid column then undergoes column fracture and disintegrates into large ligaments and droplets, which are divided into smaller droplets due to secondary breakup of bag, multimode and shear breakup [17].…”

“…This number of droplets was chosen to keep the computational cost to a manageable level even though more droplets could give slightly better resolution. The column fracture time is determined from Wu et al's [17] experiment and is defined by…”
