The critical conditions of the thermal regime in a generalized couette flow

Journal of Engineering Physics, 1969
We examine the nonisothermal steady-state flow of a Newtonian fluid between two parallel plates with consideration of the energy dissipation and in the assumption of a hyperbolic relationship between viscosity and temperature under various temperature boundary conditions.

On generalised MHD couette flow with heat transfer

Proceedings of the Indian Academy of Sciences - Section A, 1966
In the case of short-circuited generalised MHD Couette flow the rate of heat transfer, in general, increases with the increase in the value of both the Hartmann number and the pressure gradient. Especially, at the lower stationary plate it is affected by the magnetic field, which is not observed in the case of plane MHD Couette flow.

Generalized Boundary Interactions for Powder Lubricated Couette Flows

Journal of Tribology, 1996
AbstractApplication of grain flow theories to powder lubrication of hydrodynamic bearings requires careful consideration of slip of the flow velocity at the boundaries together with appropriate formulation of the fluctuation (thermal) velocity conditions at the boundaries. Generalized boundary conditions that can be applied to a wide variety of surface

Generalized annular Couette flow of a power-law fluid

Industrial & Engineering Chemistry Research, 1991
The steady laminar axial flow of a power-law non-Newtonian fluid in the annular space between two long coaxial cylinders, with one of them in motion and an imposed pressure gradient, is studied. The pressure gradient may assist or oppose the drag on the fluid due to the moving cylinder.

Generalized couette flow of a dipolar fluid between two parallel plates

Zeitschrift für angewandte Mathematik und Physik ZAMP, 1969
Dans ce travail, on presente une solution du probleme de l'ecoulement d'un fluide dipolaire entre deux plaques paralleles, dont l'une est en mouvement et l'autre fixe, en presence d'un gradient de pression. On trouve qu'il n'y a pas d'effet dipolaire sur l'ecoulement si le gradient de pression n'est pas applique, et que pour un fluide dipolaire avec λ ...

Heat Generated by MHD Couette Flow With Porous Walls

Journal of Lubrication Technology, 1975
The simultaneous effects of mass injection and magnetic field on the heat generation due to viscous dissipation is investigated analytically. The present findings are in general agreement with the temperature measurements of Chang-Yi Wang [1]. Results indicate larger reductions in maximum temperature and a significant increase in the heat take off by ...

Cyclic generation of wall slip at the exit of plane Couette flow

Journal of Rheology, 2003
Sharkskin-type melt fracture is generally produced by a discontinuous boundary condition at a die exit. In order to investigate this flow instability, a shear flow having a negative pressure gradient at the exit was generated by a wedge-shaped slider. A high-resolution differential interference contrast microscope was used for simultaneous observation ...

Generalized plane Couette flow of a polar fluid with suction or injection

Rheologica Acta, 1975
The generalized plane couette flow of a polar fluid with suction or injection with a prescribed total angular velocity at the stationary plate has been considered. The effects of variation in the parametersP x andR m characterising respectively the pressure gradient and the total angular velocity on the lower plate has been studied on the velocity and ...

Entropy generation analysis of particle suspension induced by Couette flow

International Journal of Heat and Mass Transfer, 2015
Abstract This paper describes the behavior of nanoparticle suspension under shear with non-equilibrium molecular dynamics (MD) approach. Couette flow with constant shear rate is applied to calculate its particle distribution and analyze its effect on velocity and viscosity.

Calculation of steady temperature fields in generalized couette flows of simple fluids

International Journal of Heat and Mass Transfer, 1975
Abstract A basic differential equation of the local balance of the energy flux in homogeneous simple fluids (in Noll's sense) is redeveloped for spatially and materially steady, quasi-simple shearing motions along circular (or also parallel) streamlines.
