Description
In the field of polymer injection molding, high-resolution numerical simulations play a vital role in mitigating manufacturing defects. However, the complexity of these simulations presents significant challenges, and efficient numerical analysis remains an area of ongoing research.
In this study, we present a macro-scale two-phase flow formulation for polymer injection molding. We use an in-house finite-element solver to simulate the polymer and air flows as an interfacial flow, utilizing the level-set method in a space-time framework. A space-time discretization is here of special interest when combined with adaptive time refinement. This approach enables enhanced resolution around the moving polymer-air interface without substantially increasing computational time.
We will present this methodology along with its application to high-fidelity simulations of the injection molding process. Furthermore, we will discuss the potential benefits of adaptive time refinement in improving the accuracy and efficiency of interfacial flow simulations.
