large particle modeling solver with openfoam

Virtual-iCFD · August 16, 2019, 17:39

Hi foamers,

I am looking for a solver in openfoam similar to MPM (Macroscopic Particle Model) in Fluent. The goal is to model 2-phase flow where dispersed particle size is larger than local cell size. My understanding is DPM (Discrete Phase Model) isn't sufficient to model this large particle approach. What OF solver should I look for?

Thanks!

I doubt that OpenFOAM has such solvers, but I hope that there are existing solvers that deal with such problems! You may need to implement one by yourself.

The MPM in Fluent uses the Immersed Boundary Method, and I believe it uses a linear interpolation between the fluid velocity and the solid velocity. If you are not familiar with IBM you can take a look at some review papers first.

There is an IBM in the community version of OpenFOAM:

Better even, the CFD-DEM toolkit also provides an IBM method for large particles:
