THE stresses set up in a rotating disk appear first to have been considered by Maxwell1, and the solution adopted by many engineering text-books2 shows that an axial hole, however small, halves the strength of the disk. This result, which is repugnant to physical intuition, does not appear to have been tested experimentally.

A steadily rotating plasma disk
Applied Physics, 1977A homogeneously rotating plasma disk can be formed in a radially directed Ar-arc discharge at reduced pressure with an externally applied axial magnetic field. The radial pressure distribution is measured, as well as the emitted continuum radiation and the arc voltage. With these experimental values profiles of temperature, radial and azimuthal current

On the Vibration of a Rotating Disk
Journal of Applied Mechanics, 1972The equation of motion of a rotating disk, clamped at the inner radius and free at the outer radius, is solved by reducing the fourth-order equation of motion to a set of four first-order equations subject to arbitrary initial conditions. A modified Adams’ method is used to numerically integrate the system of differential equations.

The relationship of the axisymmetric flow between large but finite coaxial rotating disks to the von Kármán similarity solution is studied. By means of a combined asymptotic – numerical analysis, the flow between finite disks of arbitrarily large aspect ratio, where the aspect ratio is defined as the ratio of the disk radii to the gap width separating ...

Direct contact melting due to a permeable rotating disk
The Physics of Fluids, 2019The melting process of a solid phase change material sitting above a heater of rotating as well as permeable disk is revisited. The melting starts due to the temperature difference between the solid and the disk, and a melt layer of thin thickness is ...

Entropy generation for flow of Sisko fluid due to rotating disk
Journal of Molecular Liquids, 2018This investigation deals with entropy generation optimization and nonlinear dissipative flow of Sisko fluid due to a rotating disk. Joule heating effect is considered. Mathematical model is obtained for the present flow problem.

Axisymmetric rotational disk braking by a curved disk
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2003AbstractThe 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.

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 ...
