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.

Large Strain Creep of Rotating Cylinders
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1961AbstractUsing 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 ...

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.

Centrifuging in Rotating Hollow Cylinders
Nature, 1936THE method described in this note provides a quick and efficient means for the fractionation of highly disperse systems—including the larger proteins—using relatively moderate centrifugal forces. Furthermore, all necessary information about the sedimentation rate and the sedimentation equilibria of these systems can be obtained, samples for examination

Electromagnetic levitation of rotating cylinders
IEE Proceedings A Physical Science, Measurement and Instrumentation, Management and Education, Reviews, 1985Stable electromagnetic levitation of spinning conducting cylindrical rotors has been demonstrated theoretically for the first time. General expressions of the quasistationary magnetic vector potential, for a rotating, conducting, cylindrical shell in the proximity of a distribution of parallel straight wires carrying currents, have been obtained by ...

Two-degree-of-freedom flow-induced vibration of a rotating circular cylinder
Ocean Engineering, 2019The flow-induced vibration (FIV) of a rotating circular cylinder in reduced velocity range of 3.0 ≤ U*≤14 is investigated numerically. The forced rotating cylinder can freely vibrate in flow and cross flow directions.

Superfluid Helium Between Rotating Cylinders
Journal of Low Temperature Physics, 1998We numerically solve the nonlinear two-fluid Hall–Vinen–Bekharevich–Khalatnikov equations for superfluid helium II confined inside a small aspect ratio Couette annulus. This simple flow configuration allows us to study how the vortex lines respond to a shear in the presence of boundaries.

We describe the critical condition necessary for the inner cylinder radius of a rotating detonation engine (RDE) used for in-space rocket propulsion to sustain adequate thruster performance. Using gaseous C2H4 and O2 as the propellant, we measured thrust
