Dynamics of phase separation of sheared binary mixtures after a nonisothermal quenching

A thermodynamics-based phase-field model is developed to simulate phase separation of a binary mixture under a temperature gradient in a constant shear. The effects of meaningful dimensionless numbers, such as the capillary number, the Lewis number, and the dimensionless heat capacity are explored. The temperature gradient breaks the symmetry of phase separation compared to instantaneous quenching while different phase separation patterns, ranging from stripes to drops, can be obtained or even suppressed by a proper choice of parameters.
