Nonturbulent flow of a viscous fluid in layers near a boundary, as that of lubricating oil in bearings.
the flow of a viscous fluid in which particles of the fluid move in parallel layers, each of which has a constant velocity but is in motion relative to its neighboring layers.
Movement of a fluid in which the motion of the particles of fluid is very orderly and all particles move along straight lines in the same direction. Laminar flow is common in viscous fluids, especially those moving at low velocities. Compare turbulent flow.
