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...

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...
Pattern selection for Darcy-Bénard convection with local thermal nonequilibrium
A weakly nonlinear analysis is performed on the classical Darcy-Bénard problem to determine the effects of local thermal nonequilibrium on the planform of convection immediately post-onset. It is found that two-dimensional rolls...

Horizontal cellular oscillations caused by time-periodic resonant thermal forcing in weakly nonlinear Darcy-Bénard convection
The onset of Rayleigh-Bénard convection in a horizontally unbounded saturated porous medium is considered. Particular attention is given to the stability of weakly nonlinear convection between two plane horizontal surfaces...

Hexagonal Cell Formation in Darcy–Bénard Convection with Viscous Dissipation and Form Drag
Recent interest in the effects of viscous dissipation on convective flows in porous media has centred almost exclusively on forced convection flows. In this paper, we investigate the manner in which it affects the onset and...

On the stability of the isoflux Darcy–Bénard problem with a generalised basic state
The scope of this study is to determine the conditions for the onset of the instability in a horizontal porous layer subject to isoflux boundary conditions and with an infinitely wide single–cell basic flow. When the...

Local thermal non-equilibrium effects in the Darcy-Benard instability with isoflux boundary conditions
The Darcy-Benard problem with constant heat flux boundary conditions is studied in a regime where the fluid and solid phases are in local thermal non-equilibrium. The onset conditions for convective instability in the plane...
The Impact of Marriage on African American Educators in Bexar County, 1880-1950
Jordan LeJeune
Apr 01, 2020
As a society, we are still having discussions about whether or not women “can have it all.” We have not moved past gendered expectations for men and women. Mollie Carey Brown, Fanny Ellis Starnes, and Lady Henrietta Boyd were...

The NF-κB transcription factor c-Rel is a critical regulator of Treg ontogeny, controlling multiple points of the stepwise developmental pathway. Here, we found that the thymic Treg defect in c-Rel-deficient (cRel-/- ) mice is...

Local thermal non-equilibrium effects in the Darcy-Benard instability with isoflux boundary conditions
The Darcy-Benard problem with constant heat flux boundary conditions is studied in a regime where the fluid and solid phases are in local thermal non-equilibrium. The onset conditions for convective instability in the plane...
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...
The effect of an embedded solid block on the onset of convection in a porous cavity
Purpose – The purpose is to determine how the presence of an embedded, centrally-placed, solid but heat-conducting block affects the onset and development of Darcy-Bénard convection.

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...

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...
