What are free energy flows in multiphase fluid dynamics?

[Shishir_93]

Hello, I am working on non linear fluid dynamics with my professor. We are trying to model multiphase flows of immiscible fluids. And my professor today asked me to look up works on 'free energy flows', but I cannot find anything on the internet that I can use, let alone understand. Can someone possibly explain and give me references to this? Anything? Thesis, published papers, textbooks, lecture notes? I thank you all in prior.

Welcome to PF;
Try looking for information about energy flow in fluid dynamics, and consider if the "free" refers to energy or flow.
