Trajectory and Breakup of Cryogenic Jets in Crossflow

摘要

An examination of the basic primary breakup characteristics and trajectories of cryogenic jet in crossflow (JICF) was performed. Breakup regimes of the cryogenic JICF were the same as those expected in a conventional JICF, with transitions between regimes being well described by a constant Weber number. A slight decrease in the transition Weber number from the bag to multimode regimes was observed with increasing q, and the transition Weber number from multimode to shear breakup was lower than previously found for laminar jets. However, both of these were attributed to differences in the jet turbulence rather than thermal effects.
