Moving Cooling Source Induced Phase Separation in Binary Liquids: an interplay of competing velocities
Lakshmipriya K, Harssh Karn, Sutapa Roy
We investigate phase separation dynamics in a binary mixture subjected to a moving cooling source from which cold temperature fronts propagate radially outward into the mixture. Th…
