  • 通过对纤维悬浮聚合物熔体的可逆和不可逆热力学过程的耦合,建立了分子链弹性哑铃模型与悬浮纤维取向描述相耦合的、具有均一 (GENERIC) 结构形式的熔体多尺度模型. 由该均一结构的多尺度模型不仅可以得出熔体不同尺度上的应力贡献,还可为一般多尺度模型方程组的建立提供其结构形式均一化的方法.

     

    Based on elastic dumbbell model of polymer melt and tensor description of fiber orientation, a mathematic multi-scale model with a general equation for the non-equilibrium reversible-irreversible coupling (GENERIC) of polymeric melt with fiber suspensions is presented by the coupling of reversible and irreversible thermodynamics. And the model provides a general framework with homogeneous GENERIC structure for the multi-scale governing equations. Through analyzing the components of GENERIC structure, stress contributions from information on different scales can be achieved.
