Nonlinear enhanced dissipation in viscous Burgers type equations II

open access: yesCommunications in Partial Differential Equations, 2023
We construct a class of infinite mass functions for which solutions of the viscous Burgers equation decay at a better rate than the solution of the heat equation for the same initial data in this class. In other words, we show an enhanced dissipation coming from a nonlinear transport term.

Wave dissipation by flexible vegetation [PDF]

open access: yes, 2011
Dissipation of waves propagating through natural salt marsh vegetation was about half the dissipation expected for rigid vegetation. This low dissipation was predicted by a theoretical model that accounts for bending of vegetation by wave motions.

Numerical Investigation of Viscous Dissipation in Elliptic Microducts [PDF]

open access: yesJournal of Physics: Conference Series, 2014
In this work a numerical analysis of heat transfer in elliptical microchannels heated at constant and uniform heat flux is presented. A gaseous flow has been considered, in laminar steady state condition, in hydrodynamically and thermally fully developed forced convection, accounting for the rarefaction effects.

Puncture of a Viscous Liquid Film Due to Droplet Falling

open access: yesFluids, 2022
Droplet impact may rupture a liquid film on a non-wettable surface. The formation of a stable dry spot has only been studied in the inviscid case. Here, we examine the break-up of viscous films, and demonstrate the importance and role of the viscous ...

Role of Viscous Dissipative Processes on the Wetting of Textured Surfaces [PDF]

open access: yesScientific Reports, 2015
AbstractWe investigate the role of viscous forces on the wetting of hydrophobic, semi-hydrophobic and hydrophilic textured surfaces as second-order effects. We show that during the initial contact, the transition from inertia- to viscous-dominant regime occurs regardless of their surface topography and chemistry.

A numerical investigation of horizontal viscous gravity currents [PDF]

open access: yes, 2009
We study numerically the viscous phase of horizontal gravity currents of immiscible fluids in the lock-exchange configuration. A numerical technique capable of dealing with stiff density gradients is used, allowing us to mimic high-Schmidt-number ...

Entropy generation analysis for viscoelastic MHD flow over a stretching sheet embedded in a porous medium

open access: yesAin Shams Engineering Journal, 2017
In this paper it is intended to analyse entropy generation by applying second law of thermodynamics to magnetohydrodynamic flow, heat and mass transfer of an electrically conducting viscoelastic liquid (Walters B′) past on a stretching surface, taking ...

Effect of Viscous Dissipation and Thermoporesis on the Flow Over an Exponentially Stretching Sheet [PDF]

open access: yes, 2019
This article analyses the influence of viscous dissipation and thermoporesis effects on the viscous fluid flow over a porous sheet stretching exponentially by applying convective boundary condition.

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...
