Flow Between Eccentric Rotating Cylinders

Journal of Lubrication Technology, 1972
The flow between eccentric rotating cylinders is studied using a modified bipolar coordinate system. The Sommerfeld pressure distribution and associated flow in a journal bearing are derived from the Navier-Stokes equations by a straightforward and systematic expansion in the clearance ratio (assumed small).

Transverse mixing in rotating cylinders

Powder Technology, 1972
Abstract The mixing of solid particles in the plane perpendicular to the axis of rotation of a simple drum mixer has been shown to occur as the result of a combination of diffusion and convection. It has been demonstrated that, to first approximation, it is necessary to consider diffusion in the radial direction only and convection in the angular ...

Effect of rotating solid cylinder on entropy generation and convective heat transfer in a wavy porous cavity heated from below

International Communications in Heat and Mass Transfer, 2018
The aim of the present study is to analyze the entropy generation and convective heat transfer in a bottom-heated wavy porous cavity containing a solid rotating cylinder.

Fluid flow between rotating cylinders

Rheologica Acta, 1975
Fluid flow between a pair of rotating cylinders with non-equal sized rolls and/or non-equal speeds of the rolls is considered for aNewtonian fluid at constant temperature. The lubrication approximation is applied as usual in the theory of calendering. A theoretical analysis of the velocity-, pressure- and shear stress distributions in the flow field is

Unsteady mixed convection in a square enclosure with an inner cylinder rotating in a bi-directional and time-periodic mode

International Journal of Heat and Mass Transfer, 2019
This work first numerically investigated the mixed convection in a cold square enclosure with an inner hot circular cylinder at Ra = 106. The cylinder rotates about its center in a time-periodic and bi-directional mode, thus the fluid is driven by both ...

Flow Between Eccentric Rotating Cylinders

Journal of Applied Mechanics, 1984
In this numerical study of flow between eccentric cylinders, the size of the separation eddy and the position of the points of separation and reattachment are found to be Reynolds number dependent. The separation point moves in the direction of rotation upon increasing the Reynolds number, in contradiction to the first-order inertial perturbation ...

Flow past two rotating cylinders

Physics of Fluids, 2011
Flow past two uniformly rotating cylinders with the same rotation rates in a side-by-side configuration is studied experimentally. The experiments are carried out at Reynolds numbers, Re, of 100, 200, 300, 400, and 500 and nondimensional rotation rates, α, varying from 0 to 5. The spacing ratios, T/D, are 1.8, 2.5, 4.0, and 7.5.
