Magnetopause and Boundary Layer
Space Science Reviews, 2005A brief overview is given of our present knowledge, observational and theoretical, of the structure of the magnetopause and the adjoining plasma boundary layer. Particular attention is given to the relationship between these electromagnetic and plasma structures on the front lobe of the magnetosphere and the magnetic field reconnection process.

This is a continuation of our earlier article concerning the boundary‐value problem where A, B are prescribed constants, and 0 < ε≪ 1 is a small positive parameter. In that article, we assumed the coefficients a(x) and b(x) are sufficiently smooth functions with the behavior given by a(x) ∼αx and b(x) ∼β as x→ 0, where α> 0 and β/α≠ 1, 2, 3,…. In

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

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.

Boundary—Layer Equations in Plane Flow; Plate Boundary Layer
2000We 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 ...

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

Viscous‐Magnetic Boundary Layers
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1974AbstractDie 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.

It is natural to think that the atmosphere rotates with the same velocity as the solid Earth although it is not at all obvious why this should happen. In general, we could say that the Earth drags the atmosphere because of the friction between the surface and the atmospheric layers near it.

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).
