Yihui Ma, Xiaoyu Xiao, Wei Li, Mathieu Desbrun, Xiaopei Liu

Abstract: Highlights•This paper proposes a new hybrid LBM-FVM solver to simulate two-phase flows which reduces memory consumption and improves computational accuracy and efficiency.•The momentum equation is solved by a set of lattice Boltzmann equations with a velocity-based high-order CM-MRT model, while the phase-field equation is solved by a WENO-based finite-volume approach.•Our solver is validated through benchmark tests, comparisons, and validation examples, both quantitatively and qualitatively.•Our massively-parallel implementation on GPU offers efficient simulation of two-phase flows for a low memory footprint.
