Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 In this paper, heat transfer coefficient, in solar collector tube under scaling conditions has been experimentally determined using a specifically fabricated test apparatus.  The effect of various variables such as  scale thickness, flow conditions and tube wall temperatures on heat transfer coefficients have been investigated. The experimental results reveals that the scale thickens has a dominating effect on heat transfer coefficient.Keywords:  Heat transfer coefficient, scale thickness, Reynold number, thermosiphon, hot water system
