Rotating Convection in a Finite Cylinder

Applied Scientific Research, 1993
When a rotating circular cylinder containing fluid is heated from below, it is observed that azimuthally travelling waves may appear in the fluid. A linear stability model is described whose numerical solutions agree well with experimental observations.

The rotating cylinder electrode

Journal of Applied Electrochemistry, 1978
The transfer of mass onto a rotating cylindrical nickel electrode was investigated at relatively low rates. The simple electrochemical reaction of ferricyanide ion in an alkali medium was applied for this purpose. In the investigations particular attention was paid to the phenomenon of the penetration of eddies into the laminar sublayer. A modification

On the Plastic Behavior of Rotating Cylinders

Journal of Applied Mechanics, 1960
Equations for strain and stress distribution in hollow rotating cylinders are developed. The deformations are considered to be of such magnitude, that the use of finite-strain theory is necessary. It is assumed that the relationship of true stress to true strain can be represented by a power relation. The three possible modes of plastic failure, namely,

The rotating cylinder rudder: The effect of cylinder roughness and cylinder gap

International Shipbuilding Progress, 1984
Tests have been made in a water tunnel to determine the effect of cylinder roughness on the performance of a model of the rotating cylinder rudder. The measurements showed that the side force developed was increased by using a rough cylinder and an additional improvement was obtained by increasing the cylinder speed ratio above the ratio found to be ...

Rotating Cylinder Planetary Gear Motor

IEEE Transactions on Industry Applications, 2015
This paper introduces a new electromechanical motor that incorporates free-spinning magnetized cylinders in the air gap. The motor has some of the features of a magnetic planetary gear in that it amplifies torque but it does so to a significantly higher degree than a conventional planetary gear with passive ferromagnetic elements in the air gap (79 ...

Elliptic and triangular instabilities in rotating cylinders

Journal of Fluid Mechanics, 2003
In this article, the multipolar vortex instability of the flow in a finite cylinder is addressed. The experimental study uses a rotating elastic deformable tube filled with water which is elliptically or triangularly deformed by two or three rollers. The experimental control parameters are the cylinder aspect ratio and the Reynolds number based on ...

Rotating Cylinder Viscometer

Review of Scientific Instruments, 1969
A rotating cylinder viscometer is described which depends for its operation upon measuring the frequency of a periodic flow. Compared with viscometers in common use, the results of this instrument are influenced to a smaller extent by end effects, difficulties of adjustment, or the requirement for high precision parts of special materials.

The elastic rotating cylinder

International Journal of Engineering Science, 1980
Abstract A fully relativistic formulation is presented for an infinitely long, elastic cylinder of constant density, rotating uniformly about its axis. The problem is reduced to a non-linear differential equation in the displacement which is linearised to obtain classical and special relativistic solutions.

Large Strain Creep of Rotating Cylinders

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1961
AbstractUsing the generally accepted assumptions of constant density, of equality of the ratios of principal shear stresses to the corresponding principal shear strain rates, and of existance of a relation between the significant strain rate and the significant stress, equations are developed for the strain rates, strains, and stresses of a rotating ...
