Abstract:In this article, we study the influence of the Rayleigh number on the natural convection of air between two square cavities. The internal cavity is subjected to a constant flow of heat while the external cavity is kept at a constant temperature. This temperature difference leads to a decrease in the density that represents the motor of the movement. Especially since the information on pressure is not sufficient, we have used the formalism vorticity current function to eliminate the pressure term in the equatio… 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.
