Interface stability refers to the tendency of an interface between different fluid regions to maintain its structure and resist disturbances. This concept is crucial when considering boundary conditions and interface problems, as it helps predict the behavior of fluids in motion, particularly when they interact with each other or with external forces. Understanding interface stability allows for better insights into phenomena such as wave formation, mixing, and the overall dynamics of fluid systems.
congrats on reading the definition of interface stability. now let's actually learn it.
