Problem about DPM (how to define injections)
 
Hello,every one!

I'm simulating an atomizer with DPM.I don't know how to set the injection properties,such as "injector inner Diam','injector outer Diam','spray half angle','relative velocity','Azimuthal angle' and so on.Can I set several injections?I hope someone can give some advice.Thanks a lot!

Hi

If you know your droplet size distribution in advance, you should consider using FLUENT's non-atomizer type models such as single, group, cone, etc.

If you are interested in the droplet size distribution itself, you may consider using atomizer type models (air-blast, pressure-swirl etc.). To start with, use FLUENT's default values. However, if you like to get a specific distribution, you will need to alter the injection parameters and/or atomizing air (if used).
