Axisymmetric rotational disk braking by a curved disk

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2003
AbstractThe hydrodynamic disk braking by an axisymmetric curved disk of arbitrary shape is investigated. A viscous fluid separates a rotating flat bottom disk and a non‐rotating axisymmetric curved upper disk. As the two disks are squeezed closer together, increased viscous torque is transmitted to the rotating bottom disk.

Rotating disk experiments

Foundations of Physics, 1978
We consider the historic Harress-Sagnac experiment in the light of our absolute space-time theory, proposing two modifications, and we give an account of its recent practical performance. We show that the effect of the rotating disk experiment is a direct result of the light velocity's direction dependence and we point out that our recently performed ...

The anisotropic rotating disks

International Journal of Mechanical Sciences, 1975
Abstract This paper analyzes the stresses generated, in closed form, in rotating disks or cylinders made of general orthotropic material. The radial and circumferential stresses in a rotating circular disk are functions of radial co-ordinates only and shear stress is equal to zero. However, the deformed shape does not remain circular.

Flow of a Viscous Liquid on a Rotating Disk

Journal of Applied Physics, 1958
Equations describing the flow of a Newtonian liquid on a rotating disk have been solved so that characteristic curves and surface contours at successive times for any assumed initial fluid distribution may be constructed. It is shown that centrifugation of a fluid layer that is initially uniform does not disturb the uniformity as the height of the ...

Evaluation of a Rotating Disk Apparatus: Drag of a Disk Rotating in a Viscous Fluid

1973
Abstract : A rotating disk apparatus, designed to attain high shear stresses comparable to those about hulls of full-scale ships is evaluated. Shear stresses were not measured but were inferred from measurements of disk moments. Two disk surfaces were evaluated, hydraulically smooth and sandpaper rough.

Free Rotating Disk

2009
This chapter represents a validation of the present integral method for the case of a single rotating disk. It was shown that the present integral method is essentially more accurate and enables modelling a wider range of the thermal boundary conditions than the methods of other authors.

RELATIVISTIC ROTATING DISK: THE GENERAL SOLUTION

Modern Physics Letters A, 1990
A general model of the piecewise-smooth spacetime whose smooth regions are the Kerr space pieces is constructed. The model includes three arbitrary constants and one arbitrary function depending on the coordinates. The Einstein tensor does not vanish only on the common boundary of the smooth regions and contains the δ-function as a factor, so that ...
