A particle interaction method called MPS (the Moving Particle Semi-implicit method), which formulates the differential operators in Navier-Stokes' equation as interactions between particles characterized by a kernel function, has been developed in recent years. We have extended this method to a two-fluid system with a potential-type surface tension in order to analize the two-phase flow without experimental correlation. This extended method (Two-Fluid MPS: TF_MPS) was successfully applied to a forced convection boiling experiment.
