چکیده
In this paper, mixed convection heat transfer of alumina-water nanofluid in an inclined and baffled c-shape enclosure is studied. It is assumed that the flow is laminar and steady. There is no energy production, energy storage and viscous heat dissipation. Also, the nanofluid is considered as a continuous, Newtonian and incompressible fluid. Governing equations are discretised by finite-difference method and solved by SIMPLE algorithm simultaneously. Reynolds number (10 < Re < 1000), rotation angle of enclosure ( < α < ), length of baffle (0.1 < Bf < 0.4), Richardson number (0.1 < Ri < 100) are changed. In addition, volume percent of nanoparticles are changed in the range of 0 < φ < 0.06. The results show that the Nusselt number increases with increase of Reynolds number. Adding nanoparticles always results in cooling enclosure. At high Reynolds number, increase of nanoparticles has less effect on the heat transfer rate. Furthermore, heat transfer increases with the Richardson number, the enclosure angle and the length of baffle.
