Has anyone tried to model multiphase jet flow mixing in tanks? I have not been able to find any tutorials similar to this type of application. Does anyone have a model that would not mind sharing?

Thanks in advance !

Hello,

I never got an answer through this forum but I did get a couple of replies in the COMSOL yahoo forum. I have been able to set up a model using the phase field method. The level set method does not work well for high velocity flows. Besides the usual multiphase flow settings, numerical stabilization is needed. Also, I set a coupling variable for the surface tension in the subdomains where fluids are present, this seemed to help.

Are you trying to model something similar?

Yep,

I've started to think about the problem... May you address me to the mentioned helpful material?
And thank you for the respond!

Hello,

I apologize for the late response.
Look carefully into the "Boiling Water" tutorial. specifically into the "delta" scalar expression for the integration coupling variables- subdomain variables. Also look at the settings for the artificial diffusion.

I integrated these changes into my model and worked fine. let me know how it goes.
