Atomisation of liquids is frequently encountered in the liquid-gas flows used in many practical chemical and process engineering applications, and an ability to reliably predict such flows is of benefit to the optimisation and performance improvement of existing equipment and processes, as well as the evaluation of retrofit options and the design of new equipment, systems and plant. This paper considers the ability of an Eulerian, two-equation continuum model of the atomisation process, embodied within a computational fluid dynamic framework, to reproduce the experimentally established behaviour of air-assisted atomisation. The influence of injector exit velocity profile, surface tension, gas velocity, and liquid and gas densities on predictions of the model is examined, and results found to be in good agreement with available experimental data.
