Stretched-exponential relaxation at a self-similiar surface

Physical Review A, 1991
The double-layer impedance at a rough electrode can be related to properties of random walks near the surface of that electrode. We apply this method to the calculation of the double-layer impedance at a self-similar electrode in two dimensions. We find that the impedance at a self-similar surface shows stretched-exponential behavior.

Stretching Cell Surface Macromolecules by Atomic Force Microscopy

Langmuir, 2001
We report the first quantitative measurement of macromolecular stretching at the surface of living cells using combined atomic force microscopy imaging and force spectroscopy. The surface of dormant spores of Aspergillus oryzae was covered with a layer of crystalline-like nanostructures (rodlets) and showed no/weak adhesion forces.

Heat transfer over an unsteady stretching surface

Heat and Mass Transfer, 2004
Similarity solution of the laminar boundary layer equations corresponding to an unsteady stretching surface have been studied. The governing time-dependent boundary layer are transformed to ordinary differential equations containg Prandtl number and unsteadiness parameter.

Heat transfer from a stretching surface

International Journal of Heat and Mass Transfer, 1993
The work deals with heat transfer from an arbitrarily stretching surface \(U\sim x^ m\) for investigating the effects of non-uniform surface temperature. Several closed form solutions for specific values of \(m\) including their numerical solutions are presented in this technical note.

Stagnation‐point Flow towards a Stretching Surface

The Canadian Journal of Chemical Engineering, 2003
AbstractAn exact similarity solution of the Navier‐Stokes equations is obtained. The solution represents steady axisymmetric stagnation‐point flow towards a stretching surface. It is shown that the flow displays a boundary‐layer structure when the stretching velocity of the surface is less than the free stream velocity.

Turbulent stretching of line and surface elements

Journal of Fluid Mechanics, 1990
Material line and surface elements transported in a turbulent velocity field increase in length or area at an exponential rate. In this paper we investigate how the stretching rates are related to the statistical properties of the velocity field both analytically and numerically in simple models of turbulence. In a Gaussian model the statistics exhibit

Stretching a Surface in a Rotating Power‐Law Fluid

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1995
The authors consider the steady flow of an incompressible power-law fluid past a horizontal stretching plate that rotates around a vertical axis. The equations are formulated for the velocity and the stress tensor. Assuming the boundary layer approximation from [the authors, Z. Angew. Math. Mech. 75, No.

ULTRA LIGHTWEIGHT SATELLITE ANTENNA WITH STRETCHED SURFACE

1999
A new telecommunication system based on inclined geosynchronous earth orbit (GEO) satellites was proposed. The system employs several inclined GEO satellites mounted with deployable phased array antennas of which apertures are 44.8m. The antennas communicate with compact mobile terminals realizing 100,000 digital voice channels.
