help me to simulate droplet breakup in T-junction

toufik08 · May 15, 2014, 15:34

Hi all,
I'm trying to simulate water in oil droplet using typical géometry (t-junction, where diamter of oil channel is double of diamter of water channel), i used VOF model, surface tension is 0.003 N/m, as boundary condition i have tried pressure inlet and velocity inlet.
For discret phase model i have used droplet breakup.
i don't know why i havn't obtained droplet breakup.
which are the important parameters that i have to verify?? should I change boundary conditons????
thank you so much

Hi , have you find the answers ? I'm working on this now and I have so many problems

I didn't receive any reply, but I since one year or more I found solution and I have published several papers with VOF simulation of droplet breakup
