Onset of convection in a variable-viscosity fluid
Journal of Fluid Mechanics, 1982The Rayleigh number R, in a horizontal layer with temperature-dependent viscosity can be based on the viscosity at T0, the mean of the boundary temperatures. The critical Rayleigh number Roc for fluids with exponential and super-exponential viscosity variation is nearly constant at low values of the ratio of the viscosities at the top and bottom ...

Conical flows of fluid with variable viscosity
Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1988Abstract It is proved that a model of a turbulent swirling vortex near a plane, which was studied by Wu (Proc. R. Soc. Lond. A 403, 235–268 (1986)), is inconsistent. There is no regular solution for a swirling downward flow satisfying the adherence condition at the surface.

Effects of variable viscosity on slider bearing
Acta Mechanica Sinica, 1986By considering the now in a slider bearing to be a nearly viscometric flow we have examined the effects of variation in viscosity, and normal stress differences on the total resistance and total normal force. We have found that under certain conditions the normal stress differences may be neglected compared with the variation in viscosity.

Variable Viscosity Jets: Entrainment and Mixing Process
2016Turbulent jets with viscosity stratification are very important from both fundamental and practical viewpoints. In this study, we carry out a comparison between Constant Viscosity Flows and Variable Viscosity Flows, in a round jet, on the basis of the same initial conditions (same jet momentum and/or the same initial Reynolds number).

Microstructure of Diverting Acids of Variable Viscosity
2021There are two ways of increasing viscosity, dilute and concentrated, in the diverting acid system, which is suitable for carbonate rock stimulation. However, the micro understanding of its viscosity increasing law is not clear.

On Journal Bearings of Finite Length With Variable Viscosity
Journal of Applied Mechanics, 1959Abstract An exact solution of the Reynolds equation for journal bearings of finite length with viscosity as a function of pressure is found. The analytical solution is expressed in terms of Heun functions. The load capacity and the attitude angle are derived.

On the plane couette flow of a variable viscosity fluid
Proceedings of the Indian Academy of Sciences - Section A, 1973In the present paper the Plane Couette flow for three cases, (i) Walls at unequal temperatures, (ii) Walls at equal temperatures and (iii) One of the walls is insulated, has been studied by taking a non-linear relation between viscosity and temperature. Exact solutions of the conpled momentum and energy equations have been obtained.

Convection in the Moon: Effect of variable viscosity
Journal of Geophysical Research, 1974This work determines criteria for stability of the lunar interior to thermal convection in the case of variable viscosity. The conditions necessary for solid convection to play an important role in the moon's revolution are determined by application of the calculated stability criteria to a variety of thermal history models.
