This presentation outlines recent developments in advancing multiphase fluid dynamics simulations using Flash-X, with a focus on notable performance improvements resulting from its integration with AMReX. The talk provides an overview of Flash-X’s composable software architecture designed for modeling diverse simulations, including solid-liquid-gas interactions, phase transitions, and chemical transport, and compares its capabilities with those of existing open-source tools and commercial products. Additionally, this presentation outlines computational workflows centered around Flash-X, emphasizing its integration with scientific machine learning models. It identifies potential research directions that leverage Flash-X to establish a robust infrastructure for composability and performance portability in incompressible multiphase flows. The ultimate goal is to apply these advancements to address real-world engineering problems.
