Plasma viscosity: A forgotten variable

Clinical Hemorheology and Microcirculation, 2008
Evaluation of plasma viscosity has been underutilized in the clinical practice. Plasma viscosity is determined by water-content and macromolecular components. Plasma is a highly concentrated protein solution, therefore weak protein–protein interactions can play a role that is not characterized by electrophoresis.

On variable viscosity magma flow

International Journal of Heat and Mass Transfer, 1989
Abstract The flow of a fluid in a pipe was treated by Poiseuille and one may find in Landau and Lifshitz a generalization of Poiseuille's solution for a fluid the temperature of which varies in a section. Platten and Legros treat a flow with a variable viscosity, but the expression for the viscosity they use, does not describe the viscosity of a ...

On the similarity of variable viscosity flows

Physica Scripta, 2016
Turbulent mixing is ubiquitous in both nature and industrial applications. Most of them concern different fluids, therefore with variable physical properties (density and/or viscosity). The focus here is on variable viscosity flows and mixing, involving density-matched fluids.

Convection in a mantle with variable viscosity

Journal of Geophysical Research, 1970
Studies are made on typical features of convection current in a thin viscous layer on a deep layer of high viscosity. The streamlines in this case are concentrated but not closed in the upper thin layer. The horizontal velocity is one sign in the upper layer and the other sign in the lower. The horizontal mass flux in the upper layer is balanced by the

Hydrodynamics of fluids of variable viscosity

Journal of Applied Mechanics and Technical Physics, 1966
An invariant Theological equation is proposed for the flow of fluids with a variable viscosity independent of time. It is shown to be desirable to distinguish a subclass of fluids with a linear fluidity law.

Onset of convection in a variable-viscosity fluid

Journal of Fluid Mechanics, 1982
The 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, 1988
Abstract 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.
