Effect of Thermal Stratification on Double-Diffusive Natural Convection in a Vertical Porous Enclosure

Convection from an inverted cone in a porous medium with cross-diffusion effects

“…Khanafer and Vafai [15] studied the double-diffusive convection in a lid-driven enclosure filled with a fluid-saturated porous medium. Kumer et al [16] investigated the effects of thermal stratification on double-diffusive natural convection in a vertical porous enclosure. In double-diffusive convection the density of the fluid mixture depends on the temperature, the concentration and on the pressure.…”

Free convection in porous media filled right-angle triangular enclosures

“…Those applications were reviewed by Nield and Bejan [10] and Ingham and Pop [11]. The natural convection in enclosures can be classified in two main groups as rectangular enclosures [12][13][14][15][16][17][18][19][20][21][22] and non-rectangular enclosures [23][24][25][26][27][28][29]. However, the number of studies on natural convection in porous non-rectangular geometries is very limited.…”

Free convection from one thermal and solute source in a confined porous medium

“…In these studies, uniform boundary conditions imposed along the vertical boundaries have been studied, including constant temperature and concentration boundaries (Goyeau et al 1996;Beji et al 1999;Bennacer et al 2001;Chamkha and Al-Naser 2001;Chamkha 2002;Costa 2004); Uniform heat and mass fluxes boundary conditions (Mamou et al, 1995); Mixing Dirichlet and Neumann boundary conditions (Mamou 2002). Besides, the linear distributions of temperature and concentration along the vertical side have been considered by Kumar et al (2002) and Kumar and Shalini (2005).…”
