In this paper, the moving particle semi-implicit (MPS) method is developed towards the simulation of multiphase incompressible flows with mass transfer due to vaporization. Traditional MPS method assumes particle volume to be constant and encounters difficulty in modeling vapor-liquid phase change due to abrupt volume change in vaporization process. In the proposed model, particle volume is assumed variable and volume change due to vaporization is considered. Particle splitting technique is developed to avoid large volume difference among particles. Source term accounting for mass transfer rate in vaporization process is developed in the pressure Poisson equation (PPE). Combined with enhanced MPS schemes developed in our previous studies, the numerical method is tested on single rising bubble, one-dimensional Stefan problem, vapor film growth around a sphere without gravity and then used in simulations of two-dimensional film boiling on both horizontal surface and cylindrical surface.
