Despite the impre ssive successes of current works, simulation of scenes containing mixing o r unmixing of high-density-ratio phases using particle-based discretizatio ns still remains a challenging task. In this paper, we propose a peridynam ics mixture-model theory that stably handles high-density-ratio multi-flui d simulations. With assistance of novel scalar-valued volume flow states, a particle based discretization scheme is proposed to calculate all the te rms in the multi-phase Navier-Stokes equations in an integral form, We als o design a novel mass updating strategy for enhancing phase mass conservat ion and reducing particle volume variations under high density ratio setti ngs in multi-fluid simulations. As a result, we achieve significantly stab ler simulations in mixture-model multi-fluid simulations involving mixing and unmixing of high density ratio phases. Various experiments and compari sons demonstrate the effectiveness of our approach.\n\nRegistration Catego ry: Full Access, Enhanced Access, Trade Exhibitor, Experience Hall Exhibit or\n\n URL:https://asia.siggraph.org/2023/full-program?id=papers_376&sess=sess209 END:VEVENT END:VCALENDAR
