Atomisation of liquid jets is achieved by injecting liquid from a nozzle at high velocity into a gaseous atmosphere. Experiments indicate the presence of a liquid core near the nozzle exit. The aim of this work is to model the disintegration into drops of this liquid core. Strong perturbations at the surface of the liquid core will experience large aerodynamic forces, and the scale of these perturbations determine the size of the liquid drops. Small drops are produced in the region of a high shear rate close to the nozzle exit and larger drops are produced in the region of lower shear some distance away. Numerical results based on an implementation of this model into existing codes agree quite well with experimental data.
