👉 A hosted fluid, also known as a fluid in a container, refers to a liquid that is physically contained within a solid or another medium, typically inside a vessel or container. Unlike free fluids that can move and flow without restriction, hosted fluids are confined to the space provided by their container, preventing them from spreading or escaping. This containment is often achieved through physical barriers like walls, membranes, or other structural elements, which maintain the fluid's integrity and prevent external contamination. Examples include liquids in pipes, reservoirs, or any enclosed space where the fluid's movement is restricted to its defined boundaries.
