I am doing spray simulation using DPM. I have attached geometry image. It is a very simple geometry.
Blue curved surface area - air inlet (to take care of atmospheric condition)
Red part- outlet (pressure outlet condition)
upper part - injector is located at the centre

I have attached model page also where I have used TAB model for breakup.

The problem is I am not getting correct results. I am getting overestimated SMD and drop size distribution when compared with experimental results.

Is there any other model which I can used for spray simulation along with TAB?(like coalescence or any other model) If not, please tell me if someone figure out any problem here.
