چکیده:

We propose in this work to study the interest of dispersing nanoparticles in a fluid to increase heat transfer by natural convection in the Rayleigh-Bénard configuration. It appears from this study that the heat flux transferred by convection laminar increases when the concentration of nanoparticles increases. However, this increase is the same order of magnitude as the concentration of nanoparticles (<8% to 10%) in the carrier fluid and incommensurate with the importance mentioned in forced convection
