reynolds number for boundary layer thickness
1Boundary-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… …
2Boundary 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… …
3Boundary 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 …
4Stokes boundary layer — in a viscous fluid due to the harmonic oscillation of a plane rigid plate. Velocity (blue line) and particle excursion (red dots) as a function of the distance to the wall. In fluid dynamics, the Stokes boundary layer, or oscillatory boundary… …
5Dynamic similarity (Reynolds and Womersley numbers) — Contents 1 Derivation 2 Dynamic similarity use 3 Boundary layer thickness 4 References 5 Exter …
6Nusselt number — In heat transfer at a boundary (surface) within a fluid, the Nusselt number is the ratio of convective to conductive heat transfer across (normal to) the boundary. Named after Wilhelm Nusselt, it is a dimensionless number. The conductive… …
7Prandtl number — The Prandtl number mathrm{Pr} is a dimensionless number approximating the ratio of momentum diffusivity (kinematic viscosity) and thermal diffusivity. It is named after the German physicist Ludwig Prandtl.It is defined as::mathrm{Pr} = frac{… …
8Ekman number — The Ekman number, named for V. Walfrid Ekman, is a dimensionless number used in describing geophysical phenomena in the oceans and atmosphere. It characterises the ratio of viscous forces in a fluid to the fictitious forces arising from planetary …
9Similitude (model) — For other uses, see Similitude (disambiguation). A full scale X 43 Wind tunnel test. The test is designed to have dynamic similitude with the real application to ensure valid results. Similitude is a concept applicable to the testing of… …
10fluid mechanics — an applied science dealing with the basic principles of gaseous and liquid matter. Cf. fluid dynamics. [1940 45] * * * Study of the effects of forces and energy on liquids and gases. One branch of the field, hydrostatics, deals with fluids at… …
