SUMMARY:High Density Ratio Multi-fluid Simulation with Peridynamics
DESCRIPTION:Technical Papers\n\nHan Yan and Bo Ren (Nankai University)\n\n
 Multiple fluid simulation has raised wide research interest in recent year
 s. Despite the impressive successes of current works, simulation of scenes
  containing mixing or unmixing of high-density-ratio phases using particle
 -based discretizations still remains a challenging task. In this paper, we
  propose a peridynamics mixture-model theory that stably handles high-dens
 ity-ratio multi-fluid simulations. With assistance of novel scalar-valued 
 volume flow states, a particle based discretization scheme is proposed to 
 calculate all the terms in the multi-phase Navier-Stokes equations in an i
 ntegral form, We also design a novel mass updating strategy for enhancing 
 phase mass conservation and reducing particle volume variations under high
  density ratio settings in multi-fluid simulations. As a result, we achiev
 e significantly stabler simulations in mixture-model multi-fluid simulatio
 ns involving mixing and unmixing of high density ratio phases. Various exp
 eriments and comparisons demonstrate the effectiveness of our approach.\n\
