Keywords:Particle method, MPS, SPH, Boiling, Gas-liquid flow, Incompressible–compressible

A multiphase particle method is developed by coupling incompressible MPS for liquid and compressible SPH for gas. The boiling model is directly modeled by inserting gas particles at the interface. Various bubble rising problems and film boiling cases validated the method.
