SUMMARY:High Density Ratio Multi-fluid Simulation with Peridynamics
DESCRIPTION:Han Yan and Bo Ren (Nankai University)\n\nMultiple fluid simul
 ation has raised wide research interest in recent years. 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
