I'm modelling mixer for two liquids: water and oil. Solver is steady, segregated, euler multiphase. Primary phase - oil, secondary - water, size - 1 mm. Mesh is tetarhedral with 1 mm step. Two liquids enter from pressure inlets (different pressures, phase fractions for sec phase are 0 and 1 respectively) and leave from pressure outlet. Solution converges very well, but when i postprocess results I dont see water fraction in outlet steram. Flux report shows reasonable amount of water and oil. Tried both steady/unstedy, mixture/euler no results.

Any ideas for solving this problem?

PS Fluent 6.1.18

do not use tetraedral meshes for this!!!!

There must be a better suggestion than that...

Can you give me one good reason for usig multiphase model.

Why not? what is the problem with tetrahedral, it is the easiest way to mesh. It is not that I wont try hexahedral, just want to know the reason. And thanks for the answer, will report on results withdifferent mesh.

Khm, didnt get the idea. Is there any alternative? If there is what is it, and thanks for help!

please go through the chemical species tutorial for defining additional scalars.

It tells u how to mix methane with air. Your problem is something similar to this.

Should be a good start.

Good luck

Ryan

Thanks, I will look at that!
