Abstract

Heat transfer performance utilizing nanofluids in a trapezoidal enclosure is investigated taking into account variable thermal conductivity and viscosity. Transport equations are modelled by a stream-vorticity formulation, and are solved numerically by the finite differ�ence method. The effects of the Rayleigh number, base angle, volume fraction, and size of nanoparticles on flow and temperature patterns as well as the heat transfer rate are pre�sented. We found that the effect of the viscosity was more dominant than the thermal con�ductivity, and there is almost no improvement in heat transfer performance utilizing nanofluids.
