Composed of, or arranged in, laminae, sheets.
laminar boundary layer
lâye-ye karâni-ye varaqe-yi
Fr.: Couche limite laminaire
In a fluid flow, layer next to a fixed boundary. The fluid velocity is zero at the boundary but the molecular viscous stress is large because the velocity gradient normal to the wall is large. → turbulent boundary layer.
Fr.: écoulement laminaire
A flow in which the particles of fluid are moving orderly, and in which adjacent layers or laminas glide smoothly over another with little mixing between them. A laminar flow may rapidly transform into a → turbulent flow for large → Reynolds numbers.
Fr.: sous-couche laminaire
A layer in which the fluid undergoes smooth, nonturbulent flow. It is found between any surface and a turbulent layer above.
