Viscous-dissipative correlations in fluctuating hydrodynamics

Journal of Physics: Condensed Matter, 1993
The time and spatial correlations of the equilibrium fluctuations in isotropic incompressible fluids are studied. The reasoning is based on the example of Brownian motion using the memory function formalism and the hydrodynamic expression of the Langevin force as an integral of the stress tensor fluctuations over the solid particle surface.

VISCOUS DISSIPATION IN THE ATMOSPHERE

Journal of Meteorology, 1961
Abstract Estimates of atmospheric viscous dissipation at various heights from near the ground to within the stratosphere have been published. All of these results, that are known to the author, are presented on a single diagram together with some new estimates made from the wind records of ordinary Sheppard-type cup anemometers mounted on a radio mast.

Viscous dissipation rate in concentrated suspensions

Physics of Fluids, 1994
The constitutive equation proposed by Phillips et al. [Phys. Fluids A 4, 30 (1992)] for shear induced particle migration in viscous flows of concentrated suspensions is used to calculate the change in viscous dissipation rate occurring when the particle distribution changes from a homogeneous state to the steady state.

Dissipative soft modes in viscous nematodynamics

Rheologica Acta, 2005
The paper analyses a possible occurrence of soft and semi-soft viscous modes in slow (low Reynolds number) flows of uniaxially anisotropic nematic liquids as described by the five parametric Leslie-Ericksen-Parodi (LEP) constitutive equations (CEs).

Viscous dissipation in steep capillary–gravity waves

Journal of Fluid Mechanics, 1997
Some simple but exact general expressions are derived for the viscous stresses required at the surface of irrotational capillary–gravity waves of periodic or solitary type on deep water in order to maintain them in steady motion. These expressions are applied to nonlinear capillary waves, and to capillary–gravity waves of solitary type on ...

Viscous dissipation in plastic pipe extrusion

Polymer Engineering & Science, 2013
We study the temperature distribution of a power‐law fluid in a pressure‐driven axial flow between eccentric cylinders in bipolar cylindrical coordinates. We begin our analysis by writing the equation of energy in bipolar cylindrical coordinates. We then obtain a dimensionless algebraic analytic solution for temperature profiles under a steady, laminar,

Viscoelastic Rotating Flow With Viscous Dissipation

Volume 7: Fluids Engineering Systems and Technologies, 2014
The rotational flow of pseudoplastic fluids between concentric cylinders is examined while dissipation due to viscous effects is taken into account. The viscosity of fluid is dependent on shear rate only. The shear rate dependence of viscosity is modeled according to the Carreau equation.

Effects of viscous dissipation in natural convection

Journal of Fluid Mechanics, 1962
The effect of viscous dissipation in natural convection is appreciable when the induced kinetic energy becomes appreciable compared to the amount of heat transferred. This occurs when either the equivalent body force is large or when the convection region is extensive.

VISCOUS ENERGY DISSIPATION IN FROZEN CRYOGENS

AIP Conference Proceedings, 2008
ITER is an international research and development project with the goal of demonstrating the feasibility of fusion power. The fuel for the ITER plasma is injected in the form of frozen deuterium pellets; the current injector design includes a batch extruder, cooled by liquid helium.

Viscous dissipation effects in magma conduits

Journal of Volcanology and Geothermal Research, 1977
Abstract Fujii and Uyeda (1974) postulated that viscous dissipation may lead to thermal instability and explosive eruptions in the case of volcanic conduits or dikes. Although their conclusions were based on a viscosity function which was valid over a very narrow temperature range, calculations presented here lead to the same result for critical dike
