This research aims to develop a micro-scale computational fluid dynamics (CFD) model for foam injection moulding to better understand gas-melt interactions and bubble formation.
Developed a micro-scale CFD framework using OpenFOAM for foam injection moulding process.
Incorporated a two-phase, compressible volume-of-fluid solver to simulate bubble dynamics.
Utilized classical nucleation theory for stochastically placing bubbles based on macro-scale conditions.
Simulations showed predicted aspect ratios and orientations consistent with skin-core behavior.
Reproduced morphology trends across plate thickness, aligning qualitatively with experimental data.
The framework advances understanding of morphology beyond basic spherical-cell models, emphasizing multiscale coupling.
