We present a novel numerical implementation of a phase-field multiphase interface tracking method within the OpenFOAM framework. Our approach solves the mass and momentum conservation equations alongside a transport equation that controls the multiphase interface thickness. Using a fractional time-stepping method, we ensure mass conservation at each time step. We extensively validated our algorithm against canonical multiphase flow problems with known analytical solutions and reference simulations with accurate interface tracking methods. Our solver demonstrated excellent interface tracking in the Rayleigh-Taylor instability problem, aligning closely with high-accuracy level-set simulations. It also accurately estimated dissipation rates in disturbed multiphase interfaces during standing wave and droplet oscillation tests. The phase-field method effectively suppressed spurious currents at the interface. Overall, our solver outperformed the standard OpenFOAM multiphase flow solver, interFoam, in terms of grid convergence and accuracy.
