It's cold, more dense fluid at the top and hot, less dense fluid at the bottom initially. The cold fluid wants to sink down, the hot fluid wants to rise up. But the two fluid compartments can't easily get past each other, and with low viscosity, some mixing happens. You find similar processes in the Earth's atmosphere when thunderstorm forms.
Could you some details on simulation. These are pretty pictures. And, I need to do something similar for my private research. Thanks
This seems cool. Wish I knew what it was. Ferrofluid mixing with a different liquid insoluble with it?
