Bubbles trapped in the fluid
 

What are the differences between these three options: [adiabatic bubbles], [thermal bubbles], and [thermal bubbles with phase change]?

Thank you.

Hello.

Adiabatic bubbles can make no heat transfer. Only pressure calculations can be done in that regions. Thermal bubbles can do heat transfer with fluid region. Both of these bubbles are second fluid, f=0.

Thermal bubbles with phase change is different. At this model, bubbles are filled with vapor of the first fluid, f=1.
