In this study, two-phase immiscible polymer blend with selective radiation heating by infrared laser is studied numerically. The phase-field model of a non-isothermal flow, which accounts for laser induced temperature field, two-phase flow with interfacial tension and marangoni effect, was developed. This model was used to simulate a droplet deforming in shear flow with various shear rate, droplet size and laser irradiation power. Based on the simulation results the effect of the selective radiation heating by infrared laser to the droplet deformation, the break-up situation and the micro-structure of the polymer blend was discussed. The paper concludes with suggestions for future research and potential applications.
