Rotating flows over a rotating disk
Ingenieur-Archiv, 1965Abstract : Local boundary layer approximations of first order are computed for axisymmetric motions which rotate over a rotating disk in the same and opposite directions. The secondary motions, which are produced by the friction forces at the rotating disk, are essentially of pure stagnation type, distorted stagnation type, cell type, and pure wake ...

Rotating Disk Electrode Method
2014In this chapter, to give readers the knowledge how to appropriately use rotating disk electrode (RDE) in their oxygen reduction reaction (ORR) study, fundamentals of both the electron transfer process on electrode surface and diffusion-convection kinetics near the rotating electrode are presented.

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 ...

An Asymptotic Solution of a Rotating Disk
Journal of Applied Mechanics, 1971The solution of the problem of a thin circular disk rotating at a constant angular velocity about its axis is obtained as a formal power series of the thickness-diameter ratio. The matching of the inner and outer expansions at a circular edge is carried out in detail for the stress conditions as well as for the displacement conditions.

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.

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 ...
