中文摘要：
短纤维增强塑料熔体是典型的具有多尺度特性的复杂流体，为研究其注射充模时微观、介观结构的演变过程，将塑料熔体中分布的纤维粒子处理成介观纤维硬棒模型，以宏观连续介质力学为基础，采用Lagrange-Euler法建立了耦合有介观纤维柱状粒子的主体流和前锋流的控制方程，并编程计算模拟出单根纤维注射填充流动的运动情况，计算结果与实际基本符合。
英文摘要：
Glass fiber reinforced polypropylene injection molding is one of very complicated fluid with multiscale structure, fibre particle is treated as rigid rod for researching microscopic and mesoscopic structure during injection molding. Based on the macroscopic continuum equation, double-scale models of main and front fluid are established by Lagrange-Euler methods, which couples both macro-scale and meso-scale. The results of single fibre flowingagree with the rule of fiber orientation.
