Flow types refer to the different ways in which a fluid can move or behave within a system. These types can be categorized into laminar flow, where the fluid moves in smooth, parallel layers, and turbulent flow, characterized by chaotic and irregular movement. Understanding flow types is essential in fields like engineering, meteorology, and medicine. In addition to laminar and turbulent flow, there are other variations such as transitional flow, which occurs between the two main types. Each flow type has distinct properties that affect how fluids interact with surfaces and other materials, influencing designs in piping systems and aerodynamics.
