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 transition — The process of a laminar boundary layer becoming turbulent is known as boundary layer transition. This process is an extraordinarily complicated process which at present is not fully understood. However, as the result of many decades of intensive … 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
Transition point — In the field of fluid dynamics the point at which the boundary layer changes from laminar to turbulent is called the transition point. Where the boundary layer becomes turbulent, drag due to skin friction is relatively high. As speed increases,… … Wikipedia
transition point — i. The point on an airfoil where the boundary layer changes from laminar to turbulent. As the speed increases, the transition point tends to move forward. As the angle of attack increases, the transition point also tends to move forward. ii. A… … Aviation dictionary
Turbulence — In fluid dynamics, turbulence or turbulent flow is a fluid regime characterized by chaotic, stochastic property changes. This includes low momentum diffusion, high momentum convection, and rapid variation of pressure and velocity in space and… … Wikipedia
Direkte 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… … Deutsch Wikipedia

Grashof number — The Grashof number mathrm{Gr} is a dimensionless number in fluid dynamics and Heat Transfer which approximates the ratio of the buoyancy to viscous force acting on a fluid. It frequently arises in the study of situations involving natural… … Wikipedia
Reynolds number — In fluid mechanics and heat transfer, the Reynolds number mathrm{Re} is a dimensionless number that gives a measure of the ratio of inertial forces ({old mathrm V} ho) to viscous forces (mu / L) and, consequently, it quantifies the relative… … Wikipedia
