Description
Summary:This study focuses on heat transfer by natural convection in a three dimensional cavity filled with nanoparticles and partially heated from the side with a uniform temperature. The opposite wall of the cavity is maintained in a cold temperature. The effect of nanofluid type on thermal phenomena within the cavity was analyzed for different sizes of the heating section, using the control volume method. The governing parameters are: the Rayleigh number (103≤Ra ≤ 105), the volume fraction (0 ≤ Φ ≤ 0.1), the heating section size (0.5≤ ≤1), and the nanofluid type. The results represent a great interest in terms of the flow and heat transfer through the cavity depending on the chosen parameters sets.
