Hello all,
I'm interested to simulate a 3d system composed of a sheet of granular particles and a gas jet upon it in variable angles relative to the horizontal sheet. The velocity of the jet should be supersonic. Now, I've seen the test case video of coupled CFDEM of the partly fluidized bed, which is similar to what I want to do, though I don't know if it suits modelling of high velocity jets with different orientations of the jet source.
Is it possible to use LIGGGHTS to simulate this system ? How complicated should that be with the current version of LIGGGHTS ?
Best,

Hi Dave,I what I did not get
Hi Dave,
I what I did not get completely - do you want to model the gas jet with LIGGGHTS? That would be possible if it's a rarified gas jet (via DSMC) but you would have to implement a granular-DSMC interaction for that.
The best option would be to use an OF sover for the supersonic flow. Basically you should be able to use the CFDEM library with any solver you desire. In this case you would have to implement a proper solver and the momentum interaction
To conclude: Sounds challenging, but it should be doable!
Cheers,
Christoph
