Abstract
This paper presents numerical simulations of two-dimensional mold filling with nematic LCPs fluids. The governing equations are solved by an efficient finite difference code that simulates the free surface flow of nematic LCPs governed by the full Ericksen-Leslie dynamic model. The numerical technique is based on a projection method and solves the equations using primitive variables for velocity, pressure, extra-stress tensor and director. An analytic solution for 2D channel flows is described and mesh refinement studies are used to verify the convergence of the methodology employed. Numerical results obtained in the simulation of mold filling are discussed.
