This dissertation investigates these multiscale challenges from complementary perspectives of representation, advection, data organization, and solver design. The first study develops a codimensional particle formulation for thin-film dynamics, coupling in-plane flow with surface deformation to model surface-tension-driven behaviors such as rupture and coalescence. The second introduces a compact, volume-conserving interface-tracking method on unstructured meshes that resolves sub-cell geometries and maintains mass conservation in complex multiphase flows. The third presents an adaptive hybrid flow-map scheme that combines grid-based and particle-based transport to preserve vortical details and reduce numerical dissipation in large-scale fluid motion. Together, these studies advance the algorithmic and computational foundations for simulating complex fluids across scales. Building on these developments, ongoing work on a matrix-free algebraic multigrid Poisson solver for adaptive octree grids extends this exploration toward a high-performance GPU-based simulation framework that unifies efficient computation with geometric and physical accuracy.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EHigh-Performance Multiscale Fluid Simulation: GPU-Based Representations, Solvers, and Adaptive Algorithms\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":": High-Performance Multiscale Fluid Simulation: GPU-Based Representations, Solvers, and Adaptive Algorithms"}],"uid":"27707","created_gmt":"2025-10-17 18:30:34","changed_gmt":"2025-10-17 18:33:22","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2025-10-27T11:00:00-04:00","event_time_end":"2025-10-27T13:00:00-04:00","event_time_end_last":"2025-10-27T13:00:00-04:00","gmt_time_start":"2025-10-27 15:00:00","gmt_time_end":"2025-10-27 17:00:00","gmt_time_end_last":"2025-10-27 17:00:00","rrule":null,"timezone":"America\/New_York"},"location":"CODA Building, Room C0908 \u201cHome Park\u201d","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
