[图书][B] Convection in porous media

DA Nield, A Bejan - 2006 - Springer
By a porous medium we mean a material consisting of a solid matrix with an interconnected
void. We suppose that the solid matrix is either rigid (the usual situation) or it undergoes …

Bidispersive double diffusive convection with relatively large macropores and generalized boundary conditions

HA Challoob, AJ Harfash, AJ Harfash - Physics of Fluids, 2021 - pubs.aip.org
This paper is concerned with the question of the beginning of convective motion in a fluid
saturated porous layer, containing a salt in solution, heated below and salted above and …

Thermal convection in a higher-gradient Navier–Stokes fluid

B Straughan - The European Physical Journal Plus, 2023 - Springer
We discuss models for flow in a class of generalized Navier–Stokes equations. The work
concentrates on producing models for thermal convection, analysing these in detail, and …

Effect of anisotropy and boundary conditions on Darcy and Brinkman porous penetrative convection

B Straughan - Environmental Fluid Mechanics, 2022 - Springer
We investigate the effects of anisotropic permeability and changing boundary conditions
upon the onset of penetrative convection in a porous medium of Darcy type and of Brinkman …

PV Brandão, LSB Alves, D Rodríguez… - Journal of Fluid …, 2023 - cambridge.org
Modal and non-modal linear stability analyses are employed to investigate the effect of
internal and external heating on disturbance temporal growth for the Darcy–Bénard …

Soret effect on the double diffusive convection instability due to viscous dissipation in a horizontal porous channel

K Roy, P Murthy - International Journal of Heat and Mass Transfer, 2015 - Elsevier
The effect of the Soret parameter on the convective stability of double diffusive convection
solely because of the viscous dissipation in a horizontal porous channel is studied. The …

Heated and salted below porous convection with generalized temperature and solute boundary conditions

B Straughan - Transport in Porous Media, 2020 - Springer
We address the problem of initiation of convective motion in the case of a fluid saturated
porous layer, containing a salt in solution, which is heated and salted below. We amplify the …

On the thermal instability induced by viscous dissipation

A Barletta - International Journal of Thermal Sciences, 2015 - Elsevier
The effect of viscous dissipation may be the sole cause of a thermoconvective instability
either in a fluid clear of solid material or in a fluid-saturated porous medium. Several recent …

Rotating convection in a higher gradient Navier–Stokes fluid

B Straughan - The European Physical Journal Plus, 2023 - Springer
We present a model for thermal convection in a horizontal layer rotating about a vertical axis,
when the fluid is an incompressible Navier–Stokes fluid of Fried–Gurtin–Musesti type. This …

Nonlinear stability for thermal convection in a Brinkman porous material with viscous dissipation

B Straughan - Transport in Porous Media, 2020 - Springer
We investigate nonlinear stability in a model for thermal convection in a saturated porous
material using Brinkman theory, taking into account viscous dissipation effects. There are (at …
