pressure swirl atomizer in 2d Axisymmetric

kev

Hi all,

Has anyone simulated the pressure swirl atomizer model within a 2D axisymmetric domain. I have a rectangular domain and every time i run the atomizer model it doesn't seem to look like a spray, as it doesnt disperse outwards. Is this normal for the axisymmetric domain? In 3-D however I can see a dispersion. I have tried with unsteady and steady case. My conditions are based on fuel injection applications.

Thanks for reading.
