Non-darcy free convection inside a wavy enclosure

Non-Darcian effects on natural convection heat transfer in a wavy porous enclosure

“…Comparison of the average Nusselt number in a cavity filled with a porous medium between the present results and that of Nithiarasu et al [21] and Chen et al [13] for various Rayleigh numbers (e = 0.9, Da = 10 À2 ).…”

“…The maximum influence of non-Darcian forces was noticed when wave phase of the wavy wall was around 300°. Recently, Sultana and Hyder [13] analyzed numerically non-Darcy natural convection inside a porous wavy-walled enclosure for various Darcy number and aspect ratio using one undulation. The enclosure consisted of two isothermal vertical wavy walls and two insulated horizontal walls.…”

Natural convection in wavy enclosures with volumetric heat sources

“…In this work, the Bejan number and the dimensionless entropy generation numbers were obtained at different wave ratios of the enclosure. Sultana and Hyder [16] investigated the nonDarcy free convection in a wavy enclosure consisting of two isothermal wavy walls using the finite-element method. Other examples in this category can be found in refs.…”

“…Moreover, many numerical investigations are performed on complex geometries of enclosures and also on sinusoidal cavities [2][3][4][5][6][7][8][9][10][11][12][13][14].…”
