ABSTRACT

The problem of natural convection induced by a temperature difference between an outer porous enclosure and an inner circular cylinder is studied in this paper. The fluid in the porous enclosure is a water-based nanofluids containing Ag, Cu, Al2O3, or TiO2 nanoparticles. The coupled momentum and energy equations have been solved numerically over a wide range of values of the solid volume fraction, the Rayleigh number, the cylinder radius, and various temperature conditions of the bottom wall. It is found that there exists an optimum cylinder radius, below which the increasing cylinder radius increases the strength of flow circulation and above which the cylinder radius decreases the strength of flow circulation. The heat transfer rate increases linearly by increasing the nanoparticles concentration for all cylinder radius and Rayleigh number.
