In this study, steady-state laminar natural convection of Cu and TiO

are studied and compared for the different curved geometries which are 1/8, 2/8 and 3/8 from the height of the enclosure. Heat transfer coefficients are presented for the enclosures with different nanofluid concentrations. The nanoparticles enhance the heat transfer. The heat transfer enhancement increases with increasing nanoparticle concentrations. A new curved enclosure is suggested to augment heat transfer.
