On the orbital response of a rotating cylinder in a current

Journal of Fluid Mechanics, 2001
A new form of dynamic response has been observed in some simple experiments with a lightly damped rotating cylinder in a current. The response is orbital with a period several times the structural natural period and an amplitude ranging up to many diameters.

THE ROTATION AND TRANSLATION OF CYLINDERS IN GENERAL RELATIVITY

International Journal of Modern Physics D, 2010
In 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 ...

Granular finger formation in a rotating cylinder

Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2003
Summary: 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, 1968
The 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.

Plastic Flow and Fracture of a Rotating Cylinder

SIAM Journal on Applied Mathematics, 1971
In 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 ...

On the filling of a rotating cylinder with a mixture

Journal of Fluid Mechanics, 1986
A rotating tank is filled from the outside with a mixture of particles and fluid. Under certain attainable conditions on the times for filling, separation, and spin-up, theory implies that the filling process acts like a centripetal separator in which heavy particles are actually concentrated at the inward-moving front.

Polytropic, differentially rotating cylinders

American Journal of Physics, 1981
Infinite cylinders composed of polytropic material can possess nearly arbitrary rotation fields while retaining the fundamental simplicity of one-dimensional structures. The physical properties of these objects can be easily calculated and understood by junior–senior level physics students even without access to a large computing facility.

Flow Separation of a Rotating Cylinder

2009
The effects of rotating a circular cylinder on the suppression of flow separation were investigated experimentally. Flow separation and vortex shedding were studied by flow visualization to guide the hot-film anemometry measurements that follow.
