Abstract
The governing equations are introduced for the viscous incompressible Newtonian fluids, in which the three-dimensional mathematical models of gas-liquid two-phase flow are established for gas-assisted injection molding (GAIM). The flow process of GAIM is simulated by coupling the level set method and the finite volume method based on non-staggered grid, which can precisely capture the gas-melt interface and the melt front surface and predict the flow features such as pressure and velocity at different time. The influences of the Reynolds numbers and the gas injection pressure are analyzed. The results indicate that the methods can capture the three-dimensional moving interfaces and predict the flow features in GAIM accurately.
