Viscous dissipation for Euler’s disk

Physical Review E, 2002
It is shown that Moffatt's recent calculation regarding the viscous dissipation of circulating air underneath a spinning coin overlooked the importance of the finite width of the viscous boundary layer. Including the enhanced dissipation in the boundary layer gives a larger dissipation from the moving air, and a scaling law of the decay of the coin's ...

Viscous dissipation in micro-channels

Journal of Mechanical Science and Technology, 2007
Viscous dissipation effects in circular micro-tubes and rectangular micro-channels were investigated theoretically in a fully developed laminar flow region. From the energy conservation law, simple theoretical equations were derived for the evaluation of the viscous dissipation effect.

Viscous dissipation in packed beds

Chemical Engineering Science, 1981
Abstract Factors affecting the magnitude of viscous dissipation in packed beds under conditions used in high pressure liquid chromatography are investigated. The free surface model is employed to characterize packed beds, to evaluate the flow field and to derive the appropriate similitude criterion for the effect of viscous dissipation. Equations for

Ionospheric Winds and Viscous Dissipation

Radio Science, 1972
Analysis of frequency distribution of vertical shear of horizontal winds is reported for 2000 samples obtained between 90 and 136 km. The distribution is independent of altitude when shears are normalized by dividing by limiting shears of .075 sec−1 below 110 km, decreasing to .035 sec−1 at 128 km.

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.

Artificial dissipation schemes for viscous airfoil computations

AIAA Journal, 1998
We examine the effect of the artificial dissipation scheme on the prediction of lift and drag in thin-layer Navier-Stokes computations of subsonic and transonic airfoil ...

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 in jets

Journal of Engineering Physics, 1988
On the basis of the boundary-layer equations we consider self-similar flow regimes of a jet with an exponential dependence of the viscosity on temperature.

Viscous dissipation in the rupture of cell–cell contacts

Nature Materials
Cell-cell adhesions mediated by adherens junctions, structures connecting cells to each other and to the cortical cytoskeleton, are essential for epithelial physical and biological integrity. Nonetheless, how such structures resist mechanical stimuli that prompt cell-cell rupture is still not fully understood.

Viscous dissipation at the Venus ionopause

Journal of Geophysical Research: Space Physics, 1982
A study of the effects of the transfer of momentum of the shocked solar wind to the Venus ionosphere near the terminator region is presented. It is shown that the deficiency of momentum flux within the velocity boundary layer in the ionosheath is comparable to the momentum flux present in the upper ionosphere near the terminator.
