SUMMARY:Particle Laden Fluid on Flow Maps
DESCRIPTION:Zhiqi Li, Duowen Chen, and Candong Lin (Georgia Institute of T
 echnology); Jinyuan Liu (Dartmouth College); and Bo Zhu (Georgia Institute
  of Technology)\n\nWe propose a novel framework for simulating ink as a pa
 rticle-laden flow using particle flow maps. Our method addresses the limit
 ations of existing flow-map techniques, which struggle with dissipative fo
 rces like viscosity and drag, thereby extending the application scope from
  solving the Euler equations to solving the Navier-Stokes equations with a
 ccurate viscosity and laden-particle treatment. Our key contribution lies 
 in a coupling mechanism for two particle systems, coupling physical laden 
 particles and virtual flow-map particles on a background grid by solving a
  Poisson system. We implemented a novel path integral formula to incorpora
 te viscosity and drag forces into the particle flow map process. Our appro
 ach enables state-of-the-art simulation of various particle-laden flow phe
 nomena, exemplified by the bulging and breakup of suspension drop tails, t
 orus formation, torus disintegration, and the coalescence of sedimenting d
 rops. In particular, our method delivered high-fidelity ink diffusion simu
 lations by accurately capturing vortex bulbs, viscous tails, fractal branc
 hing, and hierarchical structures.\n\nRegistration Category: Full Access,
