studies of natural convection in porous media have been based on Darcy's law which is applicable for slow flows and does not account for non-Darcian inertial effects. These effects represent the additional pressure drop across the porous media resulting from interpore mixing for fast flows. In this case, the total. Extensive literature on the topic is availed for porous media, Slimi et. al. [1] studied two – dimensional and transient fluid flow and heat transfer by natural convection in a vertical cylinder opened at both ends filled with a saturated porous medium and heated with a uniform lateral heat flux. The study was carried out using the File Size: KB. in heterogeneous porous media. In Chap. 5 (external natural convection) there is a substantial amount of new material inserted in the existing sections. In Chaps. 6 and 7, on internal natural convection, we now have included descriptions of the effects of a magnetic field and rotation, and there are new sections on periodic heating and on. It has been found that the results obtained by the integral method are in good agreement with those obtained by Bejan and Khair [Heat and Mass Transfer by Natural Convection in a Porous medium, Int. J. Heat Mass Transfer, 28, pp. , ]. Keywords: natural convection, porous media, heat and mass transfer. KeywordsCited by: 3.

Convective Flow and Heat Transfer from Wavy Surfaces: Viscous Fluids, Porous Media, and Nanofluids addresses the wavy irregular surfaces in heat transfer devices. Fluid flow and heat transfer studies from wavy surfaces have received attention, since they add complexity and require special mathematical techniques.   This work analyses free convection flow of a nanofluid in an inclined square enclosure consisting of a porous layer and a nanofluid layer using the finite difference methodology. Sinusoidal Cited by: The problem of nonlinear natural convection in a fluid saturated porous layer heated from below is reviewed focusing on the specific result of a collapse of the wave function. When the conditions for the onset of convection are met, a wave function is obtained as the solution of the linearized equations expressed in terms of a Fourier : Peter Vadasz.

Transport Phenomena in Porous Media contains 17 chapters and represents the collective work of 27 of the world's leading experts, from 12 countries, in heat transfer in porous media. The recent intensive research in this area has substantially raised the expectations for numerous new practical applications and this makes the book a most timely.

Abstract. Recent work on heat transfer in bidisperse porous media (BDPM) is surveyed. Topics covered are the measurement of permeability and thermal conductivity of BDPM, dispersion in BDPM, a new two-velocity two-temperature model for BDPM, and the application of that model to forced convection in a channel between two plane parallel walls.

Natural convection in porous media has attracted intensive attention from researchers in the view of its relevance in infiltrating molten metal, transport processes, extracting crude oil from oil.

The book explores how social media and other technology tools can be used to assist in the management of time-sensitive projects and shows how project portfolio management can be a tool to assist in communications with boards of directors and other governing entities.
