2020, Chinese Journal of PhysicsAn experimental study of flow and heat transfer in a differentially side heated cavity filled with coarse porous media
2019, International Journal of Heat and Mass TransferCitation Excerpt :Natural convection in enclosures differentially heated from the sides and containing porous media or solid obstacles has attracted a great deal of attention due to its fundamental nature and the broad range of applications in, for example, iron and steel making [1], food processing [2], electronics cooling [3], and indoor air conditioning [4]. Most theoretical and computational studies in the field of natural convection in differentially side heated cavities filled with porous media have been based on Darcy’s law and its extensions to include inertia and viscous diffusion effects (Forchheimer and Brinkman modifications), using so-called volume averaging over representative elementary volumes (REVs) [5–8]. This is a suitable approach when the pore length scale is much smaller than the macroscopic flow length scales.
A scale analysis for natural convection in a porous media in the presence of a magnetic field
2019, Journal of the Taiwan Institute of Chemical EngineersCitation Excerpt :A satisfactory agreement with experimental results is found. Weber [3] used the theoretical method proposed by Gill [2] to study natural convection in a differentially heated porous cavity. A satisfactory agreement with the experimental results was also obtained for the temperature distribution and the Nusselt number.
