TLDR
In this paper, the steady flow of a micropolar liquid near a rigid boundary is considered, and it is shown that while micro-inertia itself is not important, nevertheless, some properties of the microstructure do play a vital role in determining the structure of the boundary layer.Abstract:
Consideration is given to the steady flow of a micropolar liquid near a rigid boundary. It is shown that while micro-inertia itself is not important, nevertheless, some properties of the microstructure do play a vital role in determining the structure of the boundary layer. The Karman—Polhausen method is used to provide an estimate of the shear stress at the boundary, and detailed calculations are given for flow near stagnation. The important significance of the standard length of the micropolar liquid is demonstrated for this flow, as for other flows in this medium.read more

Elastico-viscous boundary-layer flows I. Two-dimensional flow near a stagnation point
D. W. Beard,K. Walters +1 more
TL;DR: In this article, the authors extended the boundary-layer theory for an idealized elastico-viscous liquid and showed that the main effect of elasticity is to increase the velocity in the boundary layer and increase the stress on the solid boundary.

The Magneto-Hydrodynamic Boundary Layer in the Two-Dimensional Steady Flow Past a Semi-Infinite Flat Plate. I. Uniform Conditions at Infinity
TL;DR: In this article, the authors investigated the effect of the magnetic field on the flow of a viscous, electrically conducting liquid past a fixed, semi-infinite, unmagnetized but conducting flat plate, where the liquid flow U and also the magnetic force H 0 at a distance from the plate are both assumed to be uniform and parallel to the plate.
