An organized flow field that can be described with streamlines In order for laminar flow to be permissible, the viscous stresses must dominate over the fluid inertia stresses
Low Reynolds number flow, in which viscous forces predominate over inertial forces Streamlines are time-invariant and convective transport is negligible
Smooth, non-turbulent Often used to describe cloud formations that appear to be shaped by a smooth flow of air traveling in parallel layers or sheets
In, or consisting of, thin plates or layers; having the form of a thin plate or lamina
flow condition with no waves, eddies etc Rarely encountered in open channel flow
Smooth, non-turbulent Often used to describe cloud formations which appear to be shaped by a smooth flow of air traveling in parallel layers or sheets
Laminar flow means the fluid is moving in smooth layers around the object Airflow becomes turbulent moving from the front to the rear of the car, forced around obstructions such as mirrors, helmets, and roll bars

In fluid flow, a smooth flow in which no crossflow of fluid particles occur between adjacent streamlines; hence, a flow conceived as made up of layers - commonly distinguished from turbulent flow
The type of fluid flow where all particles of the fluid move in paths parallel to each other and to the direction of flow, without cross motion from one path to another In general, this type of flow occurs only at very low average velocities, or in fluids having a high viscosity index
air flow in which essentially the entire body of air within a confined area moves with uniform velocity and direction as the ambient atmosphere being sampled
State of fluid flow, where the particles move along parallel, ordered paths Results in low friction on submerged surfaces, but has problems to follow retreating shapes (e g fuselage tails, airfoil behind location of maximum thickness) see also: Turbulent Flow
A flow in which fluid moves smoothly in streamlines in parallel layers or sheets The stream lines remain distinct and the flow directions at every point remain unchanged with time It is characteristic of the movement of ground water Contrasts with turbulent flow Synonymous with Streamline Flow and Viscous Flow
Smooth and regular fluid flow -- the direction of motion at any point remaining constant as if the fluid were moving in a series of layers sliding over one another without mixing
Slow, smooth flow, with each drop of water traveling a smooth path parallel to its neighboring drops Laminar flow is characteristic of low velocities, and particles of sediment in the flow zones are moved by rolling or saltation
Streamlined flow with no turbulence It is a filtration system used through virtually all clean room processing operations to control airflow and velocity at workstations within the fab The "path" the airflow takes is optimized to keep airborne particles from coming in contact with the wafers
The movement of a fluid, usually at low velocity and, therefore, at low kinetic energy levels, in which the molecules of the fluid flow along smooth parallel lines called streamlines
Nonturbulent flow of a viscous fluid in layers near a boundary, as that of lubricating oil in bearings. Fluid flow in which the fluid travels smoothly or in regular paths. The velocity, pressure, and other flow properties at each point in the fluid remain constant. Laminar flow over a horizontal surface may be thought of as consisting of thin layers, all parallel to each other, that slide over each other. It is common only where the flow channel is relatively small, the fluid is moving slowly, and its viscosity is relatively high. Examples include the flow of oil through a thin tube and blood flow through capillaries. See also turbulent flow
