laminar boundary layer laminar boundary layer[′lam·ə·nər ′bau̇n·drē ‚lā·ər] (fluid mechanics) A thin layer over the surface of a body immersed in a fluid, in which the fluid velocity relative to the surface increases rapidly with distance from the surface and the flow is laminar. laminar boundary layerA series of layers of airflow over a body with each successive layer having a higher velocity than the adjacent one and with the bottom-most layer having a zero velocity. The opposite of laminar airflow is turbulent airflow. |
