Boundary-layer thickness — This page describes some parameters used to measure the properties of boundary layers. Consider a stationary body with a turbulent flow moving around it, like the semi infinite flat plate with air flowing over the top of the plate. At the solid… … Wikipedia
Boundary layer control — In aeronautical engineering, boundary layer control (BLC) refers to a number of methods of controlling the boundary layer of air on the main wing of an aircraft. In doing so, parasitic drag can be greatly reduced and performance likewise… … Wikipedia
boundary-layer control — Methods used to control the boundary layer by sucking air through slots, making a series of small holes or porous surfaces, by blowing, or by using discrete jets. These methods can be employed to decrease drag or to increase lift on the whole or… … Aviation dictionary

Planetary boundary layer — Depiction of where the planetary boundary layer lies on a sunny day The planetary boundary layer (PBL), also known as the atmospheric boundary layer (ABL), is the lowest part of the atmosphere and its behavior is directly influenced by its… … Wikipedia
blown-boundary-layer control — A system in which the blown boundary layer uses high velocity air blown through ducts or jets to energize the boundary layer on the upper surface of the wing at low speeds, especially during approach and landing to keep the boundary layer from… … Aviation dictionary
