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 conformal field theory — In theoretical physics, boundary conformal field theory (BCFT) is a conformal field theory defined on a spacetime with a boundary (or boundaries). Different kinds of boundary conditions for the fields may be imposed on the fundamental fields; for … Wikipedia
Free surface — In physics a free surface is the surface of a body that is subject to neither perpendicular normal stress nor parallel shear stress,cite web |url=http://www.vishay.com/company/brands/measurements group/guide/glossary/freesurf.htm |title=Glossary … Wikipedia
Boundary Commission (Ireland) — The Boundary Commission was established by the Anglo Irish Treaty that ended the Anglo Irish War in 1921. Its purpose was to decide on the precise delineation of the border between the Irish Free State, which had seceded from the United Kingdom… … Wikipedia
No-slip condition — In fluid dynamics, the no slip condition for viscous fluids states that at a solid boundary, the fluid will have zero velocity relative to the boundary. The fluid velocity at all fluid–solid boundaries is equal to that of the solid boundary.[1]… … Wikipedia
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
Congo Free State Propaganda War — The Congo Free State Propaganda War (1884–1912) occurred during the era when European Imperialism was at its greatest height. Demand for oriental goods remained the driving force behind European imperialism, and (with the important exception of… … Wikipedia

Luke's variational principle — In fluid dynamics, Luke s variational principle is a Lagrangian variational description of the motion of surface waves on a fluid with a free surface, under the action of gravity. This principle is named after J.C. Luke, who published it in 1967 … Wikipedia
Airy wave theory — In fluid dynamics, Airy wave theory (often referred to as linear wave theory) gives a linearised description of the propagation of gravity waves on the surface of a homogeneous fluid layer. The theory assumes that the fluid layer has a uniform… … Wikipedia
