Break-up dynamics and drop size distributions created from spiralling liquid jets

The dynamics of the break-up of spiralling jets of Newtonian liquids were visualised. The jets were created from orifices at the bottom of a 0.085-m-diameter can rotating about its vertical axis and imaged using a high-speed camera. The effects of liquid dynamic viscosity (0.001–0.09 Pa s), rotation...

Description
Summary:The dynamics of the break-up of spiralling jets of Newtonian liquids were visualised. The jets were created from orifices at the bottom of a 0.085-m-diameter can rotating about its vertical axis and imaged using a high-speed camera. The effects of liquid dynamic viscosity (0.001–0.09 Pa s), rotation rate (5–31 rad s −1) and orifice size (0.001 and 0.003 m) upon the jet break-up and drop size distributions produced in the Rayleigh regime were investigated. The ranges of dimensionless parameters were 1< Re
