SUMMARY:Particle Laden Fluid on Flow Maps
DESCRIPTION:Technical Papers\n\nZhiqi Li, Duowen Chen, and Candong Lin (Ge
 orgia Institute of Technology); Jinyuan Liu (Dartmouth College); and Bo Zh
 u (Georgia Institute of Technology)\n\nWe propose a novel framework for si
 mulating ink as a particle-laden flow using particle flow maps. Our method
  addresses the limitations of existing flow-map techniques, which struggle
  with dissipative forces like viscosity and drag, thereby extending the ap
 plication scope from solving the Euler equations to solving the Navier-Sto
 kes equations with accurate viscosity and laden-particle treatment. Our ke
 y contribution lies in a coupling mechanism for two particle systems, coup
 ling physical laden particles and virtual flow-map particles on a backgrou
 nd grid by solving a Poisson system. We implemented a novel path integral 
 formula to incorporate viscosity and drag forces into the particle flow ma
 p process. Our approach enables state-of-the-art simulation of various par
 ticle-laden flow phenomena, exemplified by the bulging and breakup of susp
 ension drop tails, torus formation, torus disintegration, and the coalesce
 nce of sedimenting drops. In particular, our method delivered high-fidelit
 y ink diffusion simulations by accurately capturing vortex bulbs, viscous 
 tails, fractal branching, and hierarchical structures.\n\nRegistration Cat
