主　　题：non-Newtonian flow injection molding finite element method fractional step algorithm 

摘      要：The simulation of injection molding process requires a stable algorithm to model the molten polymer with non-isothermal non-Newtonian *** this paper,a staggered and iterative scheme is particularly designed to solve the velocity-pressure-temperature *** consideration of the polymer characteristic of high viscosity and low thermal conductivity,the non-Newtonian momentum-mass conservation equations are solved by the Crank-Nicolson method based split (CNBS) scheme,and the energy conservation equation with convective character is discretized by the characteristic Galerkin (CG) *** addition,an arbitrary Lagrangian Eulerian (ALE) free surface tracking and mesh generation method is introduced to catch the front of the fluid *** efficiency of the proposed scheme is demonstrated by numerical experiments including a lid-driven cavity flow problem and an injection molding problem.
