Hey all !
I was wondering if LIGGGHTS is capable of simulating a slurry mixture, or a melt of several ingredients.
I would like to simulate a rather dense mixture of several granular particles, which solidifies over time.
What , in your opinion, would be the best way to describe such a melt , if possible at all ?
what would be the most appropriate values for poisson ratio \ young's modulus, and coefficients of restitution and friction for such a mixture ?
(I know they are defined for proper solids, though i was thinking if there's any way of obtaining that limit of a melt somehow)
Thanks in advance !

To be honest, I do not know
To be honest, I do not know what the best approach would be - I think this will crucially depend on the moisture content. For a rather dry slurry, a cohesive pair style will probably do it. For wet slurry, maybe a coupled DEM-SPH approach would be considerable. A continuum approach may also be worth considering (e.g. Savage-Hutter theory in the case of avalanches).

Hi Christoph !
First of all, thanks for your reply.
Is it possible to simulate with CFD-DEM (latest version) heat exchange between the fluid and the solid particles ?
I could try using CFD-DEM to simulate the slurry with mixed solids within, but I want to be sure there is a simple way to simulate heat exchange between the two.
Thanks,
David

Hi David, a convective heat
Hi David,
a convective heat transfer model is to come at over the next few weeks (presumably by early June)

I'm looking forward to the release !
