Viscous-dissipative correlations in fluctuating hydrodynamics
Journal of Physics: Condensed Matter, 1993The 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, 1961Abstract 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, 1994The 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, 2005The 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, 1997Some 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, 2013We 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, 2014The 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, 1962The 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, 2008ITER 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.
