The test section is exposed to a constant wall temperature after filled with spherical beads. This study investigates the thermohydraulic characteristics of immiscible two-phase downward flow and heat transfer through porous media in a vertical, cylindrical, and homogeneous porous medium numerically and experimentally. Useful review articles on double-diffusive convection include those by Mojtabi and Charrier-Mojtabi (2000, 2005), Mamou (2002b), Diersch and Kolditz (2002), and Mojtabi et al. (3.26) the buoyancy effect in the momentum equation is represented by two terms, one due to temperature gradients and the other to concentration gradients.

The new feature is that beginning with Eq. The present chapter is guided by the review of Trevisan and Bejan (1990), which began by showing that the conservation statements for mass, momentum, energy, and chemical species are the equations that have been presented here in Chaps. The density gradients that provide the driving buoyancy force are induced by the combined effects of temperature and species concentration nonuniformities present in the fluid-saturated medium. In this chapter we turn our attention to processes of combined (simultaneous) heat and mass transfer that are driven by buoyancy. Covers the latest developments in research on nanofluids and CO2 sequestration.Serves as an introduction for those entering the field and as a comprehensive reference for experienced researchers.Cited over 5900 times to date in its various editions.Includes a comprehensive, 350-page reference list.Recognized as the standard reference in the field.The new edition features 2700 new references covering a number of rapidly expanding fields, including the heat transfer properties of nanofluids and applications involving local thermal non-equilibrium and microfluidic effects. As the standard reference in the field, this book will be essential to researchers and practicing engineers, while remaining an accessible introduction for graduate students and others entering the field.

The book starts with the elements of fluid mechanics and heat transfer, and covers a wide range of applications from fibrous insulation and catalytic reactors to geological strata, nuclear waste disposal, geothermal reservoirs, and the storage of heat-generating materials.

This updated edition of a widely admired text provides a user-friendly introduction to the field that requires only routine mathematics.
