Stress analysis of rotating disks☆☆☆
Nuclear Engineering and Design, 1965Abstract The equilibrium of a disk with variable thickness, symmetrical with respect to both its axis and its midplane, is analyzed, under the action of centrifugal and thermal loading. Introducing the customary assumption of plane stress, and neglecting the influence of shear stresses, the differential equilibrium equation is integrated, and stress ...

Nature, 1936
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.

Journal of Fluid Mechanics, 1987
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 ...

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 ...

Flow of a Viscous Liquid on a Rotating Disk
Journal of Applied Physics, 1958Equations 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 ...

Rotating Flow Over a Disk Sector
Journal of Applied Mechanics, 1982The rotating boundary layer flow over a plane sector of angle θs and infinite radius is solved. For sufficiently large radius the radial coordinate is eliminated by a Von Karman transformation, leaving a nonaxisymmetric flow in (θ,z), which cyclically changes over the full circle, from a Blasius boundary layer, to a Bodewadt flow, and to a rotating ...

Evaluation of a Rotating Disk Apparatus: Drag of a Disk Rotating in a Viscous Fluid
1973Abstract : 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.
