Default Problem about DPM (how to define injections)
Posts: n/a
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!

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).
