摘要

In this study, an adaptive multi-resolution moving particle semi-implicit (MPS) method is developed aiming for efficient and accurate multiphase flow simulation. The least-square MPS(LSMPS) scheme is adopted for high-order accurate operator discretization. An adaptive multi-resolution framework is developed to realize adaptive particle splitting and merging near the interface of multiphase flow. LSMPS also provides high-order interpolation of physical quantities such as velocity and pressure during particle splitting and merging. Accuracy and efficiency of the proposed method is demonstrated through convergence study and numerical simulation of static two-fluid pool, Rayleigh-Taylor instability and single rising bubble.
