Fluid-Structure Interaction

Fluid-Structure Interaction (FSI) refers to the interplay between fluids (like air or water) and solid structures (such as bridges or blood vessels). When a fluid flows around or within a structure, it can cause the structure to bend, vibrate, or deform. Conversely, the shape and movement of the structure can affect how the fluid flows. This interaction is important in various fields, from engineering and architecture to medicine, as it helps predict behavior in systems where both fluid dynamics and structural integrity are critical. Understanding FSI helps in designing safer and more efficient systems.
