Abstract:-The study of the natural convection flow and heat transfer from hot surfaces in a porous medium has been of considerable interest in energy-related engineering problems. This paper is concerned with the free convection heat transfer over an arbitrary hot surface in a porous medium. It is assumed that the fluid and solid phases are not in local thermal equilibrium and therefore a two-temperature model of heat transfer is applied. The coupled momentum and energy equations are used and transformed into ODE's. Th… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
