👉 The visited fluid, often referred to as the "visited state" or "visited fluid model," is a concept used in various scientific and engineering contexts, particularly in fluid dynamics and computational simulations. It represents the state of a fluid at a specific point in space that has been previously encountered or sampled during a simulation or experiment. This model tracks the history of fluid particles that have passed through certain regions, capturing their properties such as velocity, pressure, and temperature. By incorporating the visited fluid information, simulations can more accurately predict fluid behavior, especially in complex scenarios involving turbulence, multiphase flows, or interactions with boundaries, leading to more reliable and detailed results.
