摘要

The objective of this research is to analyze the characteristics of a liquid jet under different working fluid properties and flow rates. In this study, glycerol-water mixtures with different concentrations (Ω) were used as the working fluids. The properties of the working fluid were varied in terms of the main viscosity (μ), the diameter of the liquid column (dj), and the flow • rate (Q) to investigate the characteristics of the breakup length (Lj) and the flow type transition between a dripping and jetting flow. From the research results, when the Ω were increased the Lj and D extended and increased, respectively. Hysteresis behavior occurred in the liquid column with a larger diameter of (≥ 1146 μm), which indicated that the critical flow rate of the transition from dripping to jetting (DJ) was different from that from jetting to dripping (JD). The range of the hysteresis increased as the Ω increased and moved to a lower We number region, especially with a larger dj. It was found that increases in Ω also caused hysteresis behavior to occur in dj that without hysteresis.
