Spray simulation in fluent

chinhcd · November 5, 2013, 13:51

Hello everyone,
I have a big problem so I am looking forward to get help from you, any advice would be very much appreciated.
I have a device in picture.

I am having study about output spray characteristic: diameter, direction...and I use Ansys Fluent to simulate. However I don't know what model I should use: multiphase, discrete phase... in fluent.
I am working on a problem with multiphase - mixture, using 2d axisymmetric model but I get nothing

And in Results I didn't see any contours which shows diameter of droplet.
I would like to ask you what I should do next ? ex: choose model, steps for using to simulate.
Thank you very much.

I have same problem with you. I do not know how to model this case. Could somebody givw us any idea about that.

hm quite tricky: I think that will be a burning process accompanied with coating on the target.

Eddy Dissipation+ DPM Injection through the carrier gas.

assuming the Damkoehler Number is greather than one (turbulent mixing limited)
