👉 A nested fluid refers to a complex, layered structure where one fluid is contained within another, forming multiple levels of containment. Imagine a series of concentric cylinders or spheres where each inner layer is a fluid, and the outer layers are barriers or supports that prevent the inner fluids from escaping. This concept is often used in various scientific fields, such as biology (e.g., blood vessels within tissues), engineering (e.g., fluids in multi-layered tanks), and materials science (e.g., encapsulating substances within protective shells). The interaction between these fluids can lead to unique behaviors, such as capillary action or fluid flow through porous media, making the study of nested fluids crucial for understanding and designing systems where multiple fluid phases coexist and interact.
