Default Macroscopic particle model (MPM) for Non-Newtonian Flows?

Hi Guys,

If I remember correctly, starting from ANSYS 17.0, the MPM is added to Fluent as an addon module. It is used for fluid-particle flows where the particles are at least several times larger than the cell. By looking at its governing equations, I think it uses the idea of immersed boundary method (IBM) with linear interpolation between the fluid velocity and particle velocity (correct me if I'm wrong because I'm not 100% sure about this). This model is a great supplement to the DPM model where the particle size has to be smaller than the cell size.

My question is, has anyone done MPM simulations for non-Newtonian flows? If MPM does use the IBM or similar concepts, it should be applicable to any constitutive models right? Or, maybe a more fundamental question, does IBM care about constitutive models of the fluid?

Thanks in advance.

I double-checked the MPM module and pretty sure it uses the IBM concept, with linear interpolation between the fluid velocity and the particle velocity. I am thinking about using a different interpolation scheme for particles in non-Newtonian flows, any hints or references?
