How to model jet breakup by TAB model in ansys fluent. I have tried but it's not working out. I have chosen transient condition. Then enabled vof. phase 1-air,phase2-water, in phase interaction i gave surface tension as 0.072 and in mode transition -vof to dpm. I gave water inlet as 13m/s. Water vol fractn as 1. Method I have used -simplec. But I don't get breakup and droplets results. Can anyone guide me to incorporate both vof and dpm model. Thanks in advance

Please can you post what result you're seeing?

How to get primary and secondary breakup results. How to find the final droplet size which is hitting on the wall.

I think you need to better resolve the VOF flow first. Once the primary jet break up is visible you can worry about the DPM transition. Don't forget to turn on the dynamic adaption, there's a VOF to DPM preset to simplify things too.

Ok will on it. How create 3d animation.I have created animation by creating yz plane. But I need complete 3d animation result. How to create it.

Check documentation & Learning - I tend to just create images and then stitch them together afterwards. 

[Dharani Anbazhagan]

Ok thank you.

If possible can you please guide me by creating images on how to view 3d animation results.

If you have 3d images have a look at what's going on in the flow. At this stage the contours look too smeared to get any break up.
