Learn how to model complex fluid systems using Dyad, a Julia-based modeling and simulation tool, through this 28-minute conference talk from JuliaCon Global 2025. Explore the unique challenges of fluid system modeling, including numerical stiffness, highly non-linear behavior during phase changes and chemical reactions, complex fluid property computations for mixtures, and the dual concerns of component behavior and fluid dynamics within components. Discover how Dyad leverages Julia's multiple dispatch system to construct component models from abstract fluid representations, enabling flexible and extensible modeling approaches. Understand the framework's approach to specifying different fluids across distinct circuits within models and the user-friendly diagnostic systems that help identify and resolve modeling errors. Examine how Dyad handles thermodynamic state concepts across various fluid types and property models, providing a comprehensive solution for engineering fluid system simulations. Gain insights into advanced modeling techniques that address the intersection of component-level behavior and fluid dynamics, making complex fluid system modeling more accessible and robust.
