Recently I have been working on this. Despite its simplicity this model system is full of surprises. Our new preprint “Anisotropic particles in two-dimensional convective turbulence” is available on Arxiv https://arxiv.org/abs/1910.02882
The code for CFD I have been developing and using in the last years for Eulerian-Lagrangian studies, together with its outputs, is now presented in this brief OA article https://doi.org/10.1016/j.simpa.2019.100002
Hopefully this will help to spread it more and to be useful for other researchers. It is of course continuously updated on github: https://github.com/ecalzavarini/ch4-project
I attended the “Fourth Xiamen Symposium on Marine Environmental Sciences“, gave a talk, discussed with my collaborators and enjoyed -very much – the warm winter of Xiamen.
Babak’s paper on convective melting is out, check it here: [PRF journal]
