Abstract

In this study, MIXED CONVECTION of a water-Al2O3 NANOFLUID was numerically investigated in an open square CAVITY. All CAVITY walls were insulated and a SOLID BODY heat source was placed at the center of the CAVITY. The NANOFLUID enters the CAVITY with uniform velocity and temperature and leaves it as a fully developed flow. The governing equations were discretized using finite volume method and using Patankar’s SIMPLE algorithm. The effects of relevant parameters, such as Reynolds and Richardson numbers, length ratio (The ratio of the heat source length to the length of the CAVITY), the source thermal conductivity, and solid volume fraction of the nanoparticles were examined, both from flow field and the heat transfer rate considerations. The results show that the average Nusselt number increases with increase in Reynolds and Richardson numbers. A change in length ratio changes the flow and temperature fields. In addition, Increase of heat source thermal conductivity increases the average Nusselt number. The results also show that thermal performance of CAVITY is enhanced by increasing solid volume fraction of the nanoparticles.
