摘要
We suggest to revisit the phase separation of binary mixtures subjected to a sustained change of temperature from the point of view of reactive flows. Exploiting this new perspective, we describe the demixing dynamics by a spatial model of advection-reaction-diffusion completed with nucleation and coaguation of droplets. In this approach several features of the dynamics-in particular an oscillatory variation of the droplet density-become numerically and analytically accessible. Hence, this model helps to clarify why the oscillation frequency is hardly affected by the flow.
