Hi all,

I am writing a code for 3D, turbulent, compressible, unsteady flow in a curvilinear domain. I am at the point, where I am trying to add a subroutine that takes into consideration that the flow consists of two fluids at the same phase. I am reading some articles, but still I haven't understood what euler-euler or euler-lagrange approach is. Can you suggest me any good article that explains the situation and the different methods? Do I have to solve 2 times the momentum equations for the 2 fluids?

Thank you in advance

What I mean is if someone can explain me the difference between euler-euler and euler-lagnangian approach and the advantages-disadvantages. Thank you
