Abstract

The experimental investigation on the disintegrating behavior of a single diesel oil jet and a water-in-diesel jet, which consists of the core jet, a water jet, surrounded by a sheath of the shell jet, a diesel oil jet, was conducted. These two kinds of liquid jet will break up into distinct modes under different conditions. For the single diesel oil jet, four modes of the breakup type were observed and the dimensionless wavelength λ/D is the main controlling parameter. For the water-in-diesel compound jet, the core-to-shell mass ratio y and the dimensionless wavelength λ/D play important roles to the breakup behavior. For a core-to-shell mass ratio less than 0.5, five breakup modes were observed at varied dimensionless wavelength λ/D in our experiments. For lower water-to-diesel mass ratio, the shell jet dominates the breakup behavior mainly and the range forming the stable compound drop stream is wider than the range for the stable pure diesel drop stream. That both the single diesel oil jet and the water-in-diesel compound jet break up randomly for λ/D <3 has been found to be in good agreement with Raylegh's analysis.
