How to set up the multiPhaseEulerFoam for two or more solid phases

Dyrney · February 4, 2021, 03:46

Dear,

I would like to know if someone could help me with how to set up the "multiphaseEulerFoam" solver in the case of three phases, two solid phases (solid_1 and solid_2) and an air phase. I am facing some problems in setting up the "kinetic theory of granular flow" (e.g., restitution coefficient between solid_1 and solid_2; the granular viscous interaction between solid_1 and solid_2; etc) and the drag force (in "phaseProperties" file) between solid_1 and solid_2.

Thanks so much.

P.S. I am using OpenFOAM 8

Current kineticTheory model of multiphaseEulerFoam doesn't support the interaction between two moving solid phases.

Thank you so much for your reply.
