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...

Unstable Mixed Convection Flow in a Horizontal Porous Channel with Uniform Wall Heat Flux
A. Barletta, D. A.S. Rees
Aug 15, 2019

Buoyancy-induced instability of the horizontal flow in a plane-parallel porous channel is analysed. A model of momentum transfer is adopted where a quadratic form-drag contribution is taken into account. The basic fluid flow...

Local thermal non-equilibrium effects in the Darcy-Benard instability with isoflux boundary conditions
A Barletta, D Andrew S Rees
Jan 15, 2012
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...

Local thermal non-equilibrium analysis of the thermoconvective instability in an inclined porous layer
A. Barletta, D. A S Rees
Apr 01, 2015

The two-temperature model of local thermal non-equilibrium (LTNE) is employed to investigate the onset of secondary convective flow in a fluid-saturated porous layer inclined to the horizontal and heated from below. The layer...

The onset of convection in an unsteady thermal boundary layer in a porous medium
Biliana Bidin, D A S Rees
Dec 08, 2016
In this study, the linear stability of an unsteady thermal boundary layer in a semi-infinite porous medium is considered. This boundary layer is induced by varying the temperature of the horizontal boundary sinusoidally in time...

The effect of microstructure on models for the flow of a Bingham fluid in porous media
Sarah Nash, D A S Rees
Feb 01, 2017
The Buckingham-Reiner models for the one-dimensional flow of a Bingham fluid along a uniform pipe or channel are well-known, but are modified here to cover much more general one-dimensional configurations. These...
