Dear All,

I am new in DPM modeling.
Currently I try to use the pressure swirl atomizer model to simulate some spray characteristics results to compare with the experiment results of a particular nozzle, such as the droplet size distribution, etc.

I used the same conditions of the experiments in the simulation and found the trends of the droplet size distribution is very similar for the experiments and simulation results, however, the droplet size in simulation is much smaller than our experiment results.

One thing I am really confused is that, Can this model be used for my case? I mean to roughly predict the spray characteristics of a certain nozzle. I read both the User and Theory guide, seems there is no such comments on this part, but there are people use this model to simulate the droplet size in the references of Fluent.

Can anyone help to clarify this part? Thanks.

Regards.
