Double Diffusive Natural Convection in a Partially Layered Cavity with inner Solid Conductive Body

“…This topic subsumes to applications in geothermal reservoirs, petroleum extraction, home humidifiers, chemical catalytic reactors, prevention of subsoil water pollution, nuclear reactors, underground diffusion of nuclear wastes and other contaminants, and porous material regenerative heat exchangers [1]. The heat and mass transfer (double-diffusive) 3 in enclosed cavities composed of porous layer confined or superposed by a clear fluid are studied extensively because their vital relevant in engineering and industry. Baytas et al [2] investigated the double diffusive natural convection between a saturated porous layer and an overlying fluid layer in an enclosure using the non-Darcy flow model.…”

“…Baytas et al [2] investigated the double diffusive natural convection between a saturated porous layer and an overlying fluid layer in an enclosure using the non-Darcy flow model. Hirata et al [3] studied a linear stability analysis of thermosolutal natural convection in superposed fluid and porous layers. Islam et al [4] investigated a double diffusive natural convection in a two dimensional brine saturated porous media, subjected to vertical concentration and temperature gradients.…”

A thermo-mechanical model for flows in superposed porous and fluid layers with interphasial heat and mass exchange

“…Therefore, a single equation, describing the energy balance of the mixture, is needed to determine the temperature inside the porous region (one-equation model). Within this context, various authors have studied the stability of thermal convection in superposed fluid and porous layers; see, for example, [22][23][24][25][26][27][28][29][30][31][32][33] and references therein. More recently, the authors of [34] presented Reynolds-averaged simulations for statistically stationary turbulent heat transfer in such domains.…”

The influence of a fluid-porous interface on solar pond stability

“…An alternative modelling stance is to assume a one-domain approach, which couples the porous media flow with the viscous fluid flow in a single form of equations with highly discontinuous coefficients [10,13,14]. However, this approach is mainly used when modelling highly porous materials, where the Darcy-Brinkman equation is more appropriate, cf.…”
