The experimental setup consists of an aluminum cylinder as test section with 28 mm inside diameter and 450 mm heated length, which is subjected to a constant wall heat flux boundary condition. The Rayleigh number in this investigation was ranged from 1.08*105 to 5.8*106. Four external bodies have been used with different separation distances parameter (L/D) 1.155, 1.44, 1.77 and 2.0. The results have shown a considerable percentage of heat transfer reduction when the separation distance (L) is greater than 1/3 of the cylinder diameter while the heat transfer process suffers appreciable reduction as the separation distance (L) is less than 1/3 of the cylinder diameter. It was concluded that there is no an appreciable effect on the heat transfer reduction when the separation distance parameter (L/D) is greater than 1.77. The average Nusselt numbers were correlated with the Rayleigh numbers with empirical correlations. The results were compared with the results of a free horizontal cylinder without external body presence. 2011-09-14T08:28:08Z 2011-09-14T08:28:08Z 2008-03 Article The Journal of the Institution of Engineers, Malaysia, vol. 69(1), 2008, pages 26-31 0126-513X http://www.myiem.org.my/content/iem_journal_2008-179.aspx http://hdl.handle.net/123456789/13740 en The Institution of Engineers, Malaysia |
