Natural convection in porous cavity with sinusoidal bottom wall temperature variation

Entropy Generation During Natural Convection in a Porous Cavity: Effect of Thermal Boundary Conditions

“…(19). It may also be noted that there are three different models for viscous dissipation flow through porous media.…”

“…Effects of thermal boundary conditions, such as sinusoidal heating and discrete heating, are reported in the literature [19][20][21].…”

Effect of wall inclination on natural convection in a porous trapezoidal cavity

“…The average Nusselt number is undershooting during transient period, but constant value is obtained at steady state. Convective flow and heat transfer in a porous rectangular cavity with sinusoidal heating at the bottom wall was investigated by Saeid [2]. The average heat transfer rate is increased on increasing the heat source length and amplitude of the temperature profile.…”

Visualization of natural convection heat transport using heatline method in porous non-isothermally heated triangular cavity

“…However, non-isothermal boundary conditions are also faced in practice. The numbers of studies on nonisothermal boundary conditions are limited for enclosures filled with clear fluids [10][11][12] and cavities filled with fluid-saturated porous media [13,14]. The shape of enclosure can be different than rectangular geometry such as triangle [15,16], parallelogram [17] or trapezoidal enclosures [18][19][20][21] depending on application requirements.…”
