laminar flow

n.
Nonturbulent flow of a viscous fluid in layers near a boundary, as that of lubricating oil in bearings.

laminar flow

n
(General Physics) nonturbulent motion of a fluid in which parallel layers have different velocities relative to each other. Compare turbulent flow See also streamline flow

lam′inar flow′


n.
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.
[1945–50]

lam·i·nar flow

(lăm′ə-nər)
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.

Thus, many researchers have stated that the flow may become turbulent long before it becomes a fully developed Poiseuille flow [7, 8, 15, 28].
In the present experiments, the Rayleigh number never exceeded 1160, thus Poiseuille flow prevailed throughout the plain channel.
