1)I can use population balance equation to include the effects of processes such as breakup and coalesce. In fluent there is already a module for population balance equation and i don't need to code it yourself.
Is this available in CFX, i mean population balance equation?
and how to activated it?
2) One of them told me that:
(if you want to model the interaction between air and kerosene you have to add extra models that describes the attachment of air bubbles to a kerosene droplet, coalescense, growth, breakup, etc. There are some built-in models that cover the physical interactions (musig, beakup, coalescence for e.g. a bubble column with air dispersed in water).
How to model the interaction between bubbles and droplets?
How to add the extra models?
Thank you for help.
