Combining CVFEM and meshless front tracking in Hele–Shaw mold filling simulation

Abstract: SUMMARYIn this work, a generalized Hele-Shaw approach is developed for non-isothermal, non-Newtonian and inelastic flows arising in injection molding. The advancing free surface of the injected fluid is predicted by a novel meshless front-tracking method coupled to control volume finite element solution for the pressure. A modified Cross constitutive model with Arrhenius temperature dependence is employed to describe the viscosity of the melt and the temperature field is solved by a semi-Lagrangian scheme with… Show more

“…As for the numerical simulation of the polymer filling process, it mainly involves the solution of Navier‐Stokes (N‐S) equations, the description of the viscoelastic behaviour of the polymer melt, and the capturing of the interface front in the irregular cavity. The finite element method (FEM) has been one of the most popular methods to deal with the two‐phase flow in the filling process. In 2008, Li et al simulated the polymer injection molding process using the adaptive coupled arbitrary Lagrangian‐Eulerian finite element and meshfree method.…”
