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 ...

Comparative investigation of five nanoparticles in flow of viscous fluid with Joule heating and slip due to rotating disk

, 2018
Present article addresses the comparative study for flow of five water based nanofluids. Flow in presence of Joule heating is generated by rotating disk with variable thickness.

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.

Joule heating and viscous dissipation in flow of nanomaterial by a rotating disk

, 2017
This paper aims to analyze the flow of second grade nanoliquid by a rotating disk. Nanofluid under investigation strongly depends upon Brownian motion and thermophoresis. Heat transfer is studied subject to dissipation and Joule heating.

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 ...
