The governing equations are solved using a second-order accurate finite volume approach with a staggered grid system. The classical projection method is used to handle the velocity-pressure coupling. The effects of monitoring parameters, namely, Richardson number, Reynolds number, and solid volume fraction on the streamline and isotherm contours as well as average Nusselt number along the two heat sources are carried out and discussed in based range for Reynolds number 10 ≤ Re ≤ 500, Richardson numbers 0.1 ≤ Ri ≤ 10, and the solid volume fraction 0 ≤ Φ ≤ 0.1. The results show that by adding the nanoparticles to base fluid and increasing both Reynolds and Richardson number the heat transfer rate is enhanced. It is also found that, regardless of the Richardson number, Reynolds number, and the solid volume fraction of nanoparticles, the highest heat transfer enhancement occurs at the left heat source surface.
