Multiphase Flow with Non-Newtonian Liquid

Project Support
1

Is it possible to use the multiphase flow solver to calculate the fluid flow of a melted polymer (non-newtonian) fluid coming out of a nozzle to air? Or does the fluid have to be a newtonian liquid?

Thanks,
Eric

Hi Eric!

In theory there shouldn’t be any issue unless for some reason OpenFOAM dosen’t like how non-Newtonian fluids react in multiphase flow but that seems rather unlikely. Why don’t you start a project out and see if it manages to run?

Cheers!

Thanks for the reply. I will set one up. Just thought I would ask a question before I wasted my time.

Thanks again,
Eric

Hi @eweber, there is an example of a non-Newtonian fluid multiphase of concrete in a mold here:

might be of use to you.

Best,
