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.

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.

THE ROTATION AND TRANSLATION OF CYLINDERS IN GENERAL RELATIVITY
International Journal of Modern Physics D, 2010In general relativity, the gravitational field of an infinite rotating cylinder is globally (but not locally) different from that of a static cylinder. It is shown here that, for an infinite rigidly translating (non-rotating) cylinder of perfect fluid with a regular axis, there exists a (translating) frame of reference relative to which the ...

Elliptic and triangular instabilities in rotating cylinders
Journal of Fluid Mechanics, 2003In 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 ...

Plastic Flow and Fracture of a Rotating Cylinder
SIAM Journal on Applied Mathematics, 1971In this study T. Y. Thomas’ theory of fracture is applied to determine the velocity field of a long cylinder that rotates about its longitudinal axis of symmetry.The cylinder is made of a rigid-ideally plastic material that obeys von Mises’ condition of plasticity.The loading history of the cylinder is studied with particular attention to the plastic ...

Centrifuging in Rotating Hollow Cylinders
Nature, 1936PROBLEMS in particle size analysis in disperse systems may be divided in general into two classes, namely, those involving the determination of the size or molecular weight of particles comprising the disperse phase of a monodisperse system, and those involving the determination of the particle size distribution function for the disperse phase of a ...

Granular finger formation in a rotating cylinder
Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2003Summary: It is well known that the front of a fluid sheet flowing over an inclined surface is unstable to spanwise perturbations. This instability, which manifests itself in the formation of fingers of fairly constant wavelength, reflects a competition between viscous stresses and surface tension.

Aerodynamic Sound Generated by a Rotating Cylinder
The Journal of the Acoustical Society of America, 1968The flow generated by a sinusoidally rotating cylinder immersed in a viscous and slightly compressible fluid is calculated as a singular perturbation problem (in the Mach number). It is found that the transverse waves in the boundary layer are not sufficient to satisfy all conditions of the problem but that longitudinal waves have to be added.
