boundary-layer transition
11Ekman layer — In standard boundary layer theory, the effects of viscous diffusion are usually balanced by convective inertia. When a fluid rotates, however, the dominant balance may instead be struck between diffusion effects and the Coriolis force. Under… …
12K–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 …
13Ekman layer — The layer of transition between the surface boundary layer, where shearing stress is constant, and the free atmosphere, where the atmosphere is treated as an ideal fluid in approximate geostrophic equilibrium. Also called a spiral layer …
14Double layer (plasma) — This article is about the structure in plasma physics. For other uses, see Double layer. Saturnian aurora whose reddish colour is characteristic of ionized hydrogen plasma.[1] Powered by the Saturnian equivalent of (filamentary) Birkeland… …
15Grain boundary — A grain boundary is the interface between two grains in a polycrystalline material. Grain boundaries disrupt the motion of dislocations through a material, so reducing crystallite size is a common way to improve strength, as described by the Hall …
16Decision boundary — In a statistical classification problem with two classes, a decision boundary or decision surface is a hypersurface that partitions the underlying vector space into two sets, one for each class. The classifier will classify all the points on one… …
17K-T boundary — noun The geological signature of the transition between the Cretaceous period and the Tertiary period 65.5 million years ago.This transition is marked worldwide by a layer of material that contains a high level of Iridium …
18Direkte Numerische Simulation — Unter Direkter Numerischer Simulation, kurz DNS, versteht man die rechnerische Lösung der vollständigen instationären Navier Stokes Gleichungen. Sie unterscheidet sich von anderen Berechnungsmethoden der Strömungsmechanik dadurch, dass… …
19Lineare Stabilitätstheorie — Die Lineare Stabilitätstheorie (kurz LST) beschreibt physikalisch in einer Strömung das Anwachsen wellenförmiger Störungen mit kleiner Amplitude. Durch Vorgabe eines stationären Strömungsfeldes lassen sich Anfachungsraten und Form der linearen… …
20Orr-Sommerfeld-Gleichung — Dieser Artikel befasst sich mit dem Anwachsen kleiner Störungen in einem Strömungsfeld. Für weitere Bedeutungen des Begriffs Lineare Stabilitätstheorie siehe Stabilitätstheorie. Die Lineare Stabilitätstheorie (kurz LST) beschreibt in einer… …
