Abstract

The flow dynamics of two-dimensional liquid jets issued into still air were experimentally studied. Three injectors with a thickness of 0.35 mm and aspect ratios of 30, 60 and 90 were used. The experiments were performed for volume flow rates ranging from 10 to 120 liter per hour. High speed photography was employed for capturing physics of the jet flows. The flow development of two-dimensional liquid jets was categorized into four groups including 1) dripping regime, 2) column regime, 3) triangular regime, and 4) perforation regime. Also, different parameters of liquid sheet such as convergence angle, convergence length, and retraction velocity were also measured. The obtained results showed that the convergence length of the jets increases with aspect ratio. Furthermore, it was revealed that the convergence angle and retraction velocity were independent of the aspect ratio. Based on the experimental data, several empirical relations were developed for description of different flow parameters.
