... ¯ dropped to values that were roughly 60% lower than that in the concentric case. This demonstrates that high eccentricity causes a deterioration of heat transfer not only in the narrow gap region but also in the entire annulus. 1 Corresponding author.

... and nanoparticle size. It was observed that for Ra ≥ 10 4 , the average Nusselt number was deteriorated by increasing the volume fraction of nanoparticles. However, for Ra = 10 3 , the average Nusselt number enhancement depends on aspect ratio of the annulus as well as volume fraction of nanoparticles. Also...
