Effect of swirl on turbulent surface fluctuations in swirl nozzle atomizers is investigated based on a model of fluid elements moving in Lagrangian frame. The model indicates turbulence can be suppressed by swirl. The model is verified by performing a set of experiments on swirl nozzles, which keeps the internal turbulence level relatively constant and changes only the level of swirl. This is achieved by using nozzles with different swirl inserts to change the tangential inlet velocities and keep the jet velocity at the nozzle exit constant. It is shown that increasing the swirl suppresses surface fluctuations.
