An injector model for atomization of liquid fuel using a low pressure atomized gas. The model is focused to mix a volume of liquid fuel with a volume of corresponding atomizing gas to obtain a pressurized liquid fuel-gas mixture. This liquid-gas mixture is ejected through a discharge orifice into a lower combustion chamber pressure, as a result of which the liquid fuel breaks up into ligaments. The atomized gas emerges from the liquid fuel-gas mixture as a result of pressure jump and further enhances this break-up of liquid fuel into smaller droplets and promotes combustion of these droplets in the chamber.
