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 egory: Full Access, Full Access Supporter\n\nLanguage Format: English Lang uage\n\nSession Chair: Kui Wu (LightSpeed Studios) URL:https://asia.siggraph.org/2024/program/?id=papers_407&sess=sess144 END:VEVENT END:VCALENDAR
