Plasma-wall boundary layers

Physical Review E, 1999
According to a well established result, boundary layers develop in plasmas near solid surfaces. By means of a one-dimensional two-fluid model, we analyze the influence of charge separation and ion viscosity upon the layer structure. This leads to a critical discussion of the Bohm criterion. We find that, in the viscous limit, quasineutrality holds even

Unsteady Boundary Layers

IMA Journal of Applied Mathematics, 1984
Based mainly upon results obtained at the Queen Mary College in London a brief outline of the characteristics of unsteady laminar and turbulent boundary layers is presented. Superimposed on a steady mean motion are oscillatory standing or traveling waves. \textit{M. J.

Viscous‐Magnetic Boundary Layers

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1974
AbstractDie Lösung des allgemeinen Problems der viskomagnetischen Grenzschicht wird mit Hilfe asymptotischer Entwicklungen des zugehörigen singulären Störungsproblems behandelt. Dabei werden diejenigen Situationen betrachtet, bei denen sich das Vorhandensein zweier Grenzschichtbereiche erkennen läßt.

Boundary—Layer Equations in Plane Flow; Plate Boundary Layer

2000
We now wish to treat flows with very small viscosity or very high Reynolds numbers. An important contribution to the science of fluid motion was made in 1904 by L. Prandtl (1904). Prandtl showed the manner in which the viscosity has its effect for high Reynolds number flows and how the Navier–Stokes differential equations can be simplified to yield ...

Bottom Boundary Layer

2014
In marine geosciences, the bottom boundary layer (BBL) refers to a layer of flow in the immediate vicinity of the solid sea bottom where the effects of viscosity are significant in determining the characteristics of the flow. The BBL was first discovered by Prandtl (1905) in aerodynamics and subsequently applied to other fluids moving on the surface of

Chemical nonequilibrium boundary layer

AIAA Journal, 1963
The nonequilibrium boundary layer is considered as a binary mixture of atoms and molecules with finite dates of dissociation and recombination. To obtain accurate solutions to the partial differential equations for this type of flow without any necessary simplifying assumptions, an implicit finite-difference scheme is developed for solving these ...

Boundary Layers

2017
Transient effects in elastohydrodynamic lubrication occur due to varying operating conditions and surface features moving through the contact. For rolling/sliding contacts the lubricated contact behaviour is determined by a unifying mechanism characterized by the inlet length (boundary layer).
