Multiscale simulation of a well-entangled polymer melt flow in between two coaxial cylinders under non-isothermal condition
ORAL
Abstract
We have successfully extended a multiscale simulation method to non-isothermal well-entangled polymer melt flows in between two coaxial cylinders. At the microscopic level, a dual slip-link model is employed as a model for well-entangled polymers. We found that the extended multiscale simulation method is quite effective to reveal the relation between non-isothermal polymeric flows and microscopic states of polymer chains expressed by primitive paths and slip-links. It is also found that the temperature-dependent reptation-time-based Weissenberg number is a suitable measure to understand how extent polymer chains are deformed in a range of the shear rate used in this study.
