Abstract

Heat Transfer enhancement in turbulent natural convection using nanofluids is investigated numerically. The problem used for studying natural convection is a differentially heated square enclosure. The Bousinessq model is used to model density variation in the nanofluid. The transport equations are solved numerically using a second-order finite volume technique by implementing the k-ω model. The numerical solution is benchmarked against the experimental results of Ampofo and Karayiannis [10]. The Prandtl number and the Rayleigh number of the base fluid are set equal to 6.57 and 1010 respectively. The presence of nanoparticles is found to enhance the heat transfer in the enclosure.
