The Effect of Internal and External Heating on the Free Convective Flow of a Bingham Fluid in a Vertical Porous Channel
We study the steady free convective flow of a Bingham fluid in a porous channel where heat is supplied by both differential heating of the sidewalls and by means of a uniform internal heat generation. The detailed temperature...

Darcy-Bénard-Bingham convection
D A S Rees
Aug 31, 2020
The present paper is the first to consider Darcy–Bénard–Bingham convection. A Bingham fluid saturates a horizontal porous layer that is subjected to heating from below. It is shown that this simple extension to the classical...

The effect of conducting sidewalls on the onset of convection in a porous cavity
In this short paper we consider the effect of the presence of conducting sidewalls of finite thickness on the onset of convection in a two-dimensional porous cavity. Two cases are considered where the outer boundaries of the...

Weakly nonlinear convection in a porous layer with multiple horizontal partitions
We consider convection in a horizontally uniform fluid-saturated porous layer which is heated from below and which is split into a number of identical sublayers by impermeable and infinitesimally thin horizontal partitions. Rees...
The convection of a Bingham fluid in a differentially-heated porous cavity
D A S Rees
May 01, 2016
Purpose – The purpose is to determine the manner in which a yield-stress fluid begins convecting when it saturates a porous medium. A sidewall-heated rectangular cavity is selected as the testbed for this pioneering...
Free Convection of a Bingham Fluid in a Differentially-Heated Porous Cavity
D. Andrew S. Rees
Mar 31, 2022
We examine how a square-grid microstructure affects the manner in which a Bingham fluid is convected in a sidewall-heated rectangular porous cavity. When the porous microstructure is isotropic, flow arises only when the...

The onset of convection in a porous layer with multiple horizontal solid partitions
The principal objective of the present paper is to investigate the onset of convection in a horizontal layer heated from below which consists of distinct porous sublayers which are separated by solid heat-conducting partitions....

The red edge excitation shift phenomenon can be used to unmask protein structural ensembles
To understand complex molecular interactions it is necessary to account for molecular flexibility and the available equilibrium of conformational states. Only a small number of experimental approaches can access such...
A thermodynamic model for interpreting tryptophan excitation-energy-dependent fluorescence spectra provides insight into protein conformational sampling and stability

Dec 03, 2021
It is now over thirty years since Demchenko and Ladokhin first posited the potential of the tryptophan red edge excitation shift (REES) effect to capture information on protein molecular dynamics. Whilst there have been many key...

Nonlinear convection in a partitioned porous layer
D A S Rees
Dec 08, 2016
Convection in a partitioned porous layer is considered where the thin partition causes a mechanical isolation of the two identical sublayers from one another, but heat may neveretheless conduct freely. An unsteady solver that...
On convective boundary layer flows of a Bingham fluid in a porous medium
D A S Rees
Mar 01, 2015
In this short paper we consider the state-of-the-art with regard to convective boundary layer flows of yield-stress fluids in a porous medium. About a dozen papers have been published on the topic in the last 15 years or so and...

© 2016 Gold Open Access: this paper is published under the terms of the CC-BY license. Rare earth elements (REEs) generate characteristic absorption features in visible to shortwave infrared (VNIRSWIR) reflectance spectra....
Convective flow of a bingham fluid in internally heated porous cavities
D A S Rees
Mar 31, 2021
We study the onset of convection within a rectangular porous cavity which is saturated with a Bingham fluid and subjected to a uniform internal heat generation. When such a cavity is saturated by a Newtonian fluid, convection...

Three-dimensional convective planforms for inclined Darcy-Bénard convection.
We investigate the onset of convection in an inclined Darcy-Bénard layer. When such a layer is unbounded in the spanwise direction it is generally known that longitudinal rolls comprise the most unstable planform. On the other...
