👉 An integrating fluid, often used in the context of fluid dynamics and thermodynamics, is a substance that facilitates the mixing and interaction of different fluids or phases within a system. It acts as a medium through which properties like temperature, pressure, and concentration can be uniformly distributed, allowing for the analysis of complex fluid behaviors. In engineering applications, integrating fluids are crucial for processes like heat exchangers, chemical reactors, and environmental systems, where efficient mixing and transfer of energy or mass are essential. These fluids can be liquids, gases, or even supercritical fluids, each offering unique properties that make them suitable for specific applications in maintaining system efficiency and performance.
