👉 A layer fluid, also known as a stratified flow or laminar flow in fluid dynamics, is a type of fluid flow where the fluid layers slide over each other without significant mixing. This occurs when the fluid layers have different densities or viscosities, causing them to form distinct, parallel layers that maintain their separation. The lower-density fluid remains at the top, while the higher-density fluid stays at the bottom, creating a stable stratification. This phenomenon is common in natural settings like ocean currents and atmospheric layers, where temperature, salinity, or other properties cause the fluid to separate into distinct layers. The layer fluid is characterized by minimal turbulence and a smooth, orderly movement of the fluid layers.
