Outline of Final Research Achievements

The research aimed at proposing an accurate, reliable particle-based computational tool for practical simulations of two-phase gas-liquid flows. During the first phase of this research an accurate two-phase particle method was developed and rigorously verified. This part of research was published in Journal of Computational Physics. The developed multiphase method was characterized by a mathematically-physically consistent scheme for interface density modeling based on Taylor series expansion. The scheme could tackle the mathematical discontinuity of density at the interface and could also keep the sharpness of spatial density variations. Although the second phase of research was initially devoted to GPU-based implementation of the developed multiphase code, the method was decided to be further enhanced for a comprehensive and accurate modeling of multiphase flows, including surface tension and turbulence modeling. An accurate surface tension model was then proposed.
