Boundary layer — For the anatomical structure, see Boundary layer of uterus. Boundary layer visualization, showing transition from laminar to turbulent condition In physics and fluid mechanics, a boundary layer is that layer of fluid in the immediate vicinity of… … Wikipedia
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
Shape factor (boundary layer flow) — A shape factor is used in boundary layer flow to determine the nature of the flow.:H= frac {delta^*}{ heta}where H is the shape factor, delta^* is the displacement thickness and θ is the momentum thickness. Displacement thickness is defined as… … Wikipedia
boundary-layer normal-pressure drag — A drag resulting from the shape of the body. Streamlining the exposed parts can reduce boundary layer drag. See also form drag … Aviation dictionary
Shape factor — can refer to one of number of values in physics, engineering or image analysis. Typically, a shape factor refers to a value that is affected by an object s shape but is independent of its dimensions.In physics: * A band pass filter performance… … Wikipedia
K–T boundary — The K T boundary is a geological signature, usually a thin band, dated to 65.5 ± 0.3 (mya). [ [http://www.stratigraphy.org/cheu.pdf International commission for Stratigraphy] ] K is the traditional abbreviation for the Cretaceous Period, and T is … Wikipedia
Convergent boundary — In plate tectonics, a convergent boundary, also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of lithosphere move toward one another and collide. As … Wikipedia
