Comparisons are discussed of computed and measured transient sprays from an air-assisted fuel injector. Although the measurements were extensive, they did not characterize fully the conditions at the nozzle exit which had to be obtained from a simple model of the flow within the injector. It is found that spray width, spray tip penetration, amount of spray found in the head vortex, and chamber fuel distribution are strong functions of the internal design of the fuel injector. Particularly important are the drop size distribution and the direction of the flow at the exit of the nozzle.
