DPM-Number of streams in pressure swirl atomizer

Zari · February 6, 2017, 06:34

I want to model a single hole-solid cone injection of a liquid. The model is 2D-axisymmetric swirl. I have chosen pressure-swirl atomizer, since the cone models are only available in 3D, then I know that the model will consider hollow-cone (is this correct?).

the liquid flow rate is 1.4 g/s.
spray half angle: 30 deg.
upstream pressure: 4 atm.
Injector inner diameter: 0.2 mm

How should I decide about entry of 'number of streams'??

I looked at many forums and at the Fluent manual, seems that the number of streams will be used for calculation of mass of every particle.

Since we enter the total injection flow rate, pressure, and injector diameter, it is expected that the number of the streams could be calculated. I am confused about this entry.

How the 'number of streams' and mass flow rate of fuel are related to each other?
