In this video, we demonstrate a range of fluid dynamics applications supported by the exascale-ready community code, Flash-X. Built on AMReX's block-structured adaptive mesh refinement framework, Flash-X is designed to push the boundaries of high-fidelity multiphase simulations. We highlight the relationship between simulation fidelity and the corresponding wall time for applications such as liquid-jet in crossflow, pool and flow boiling, and solid-fluid-gas dynamics in simulations involving impinging liquid jets and the water-entry of solids from air.
