“…They suggested that heat transfer data can be correlated by using heat momentum transfer analogy instead of Dittus-Boelter type equation. Copetti et al [17] compared experimentally heat transfer and friction characteristics of smooth and microfin tubes at different flow rates from a laminar to a turbulent flow using water as test fluid. They developed an empirical correlation for prediction of microfin tube heat transfer data and compared them with experimental results.…”

“…The directly comparable works available on this subject are those of Al-Fahed et al (1993), Chiou et al (1995), and the i n t e r n a t i o n a l j o u r n a l o f r e f r i g e r a t i o n 3 1 ( 2 0 0 8 ) 2 3 4 -2 4 1 most recent work of Copetti et al (2004). These experimental studies present average Nusselt numbers from the experimentally obtained data with water as the test fluid.…”

“…Schlager et al, 1990;Ishikawa et al, 2002;Col et al, 2002), but the singlephase heat transfer and flow characteristics of micro-fin tubes are not well established as results reported are scarce and non-consistent, thus leading to a serious lack of single-phase design data. For example, in the turbulent flow region Khanpara et al's (1987) single-phase heat transfer data indicate that Nu number is proportional to Re 1.7 Pr 0.4 whereas Al-Fahed et al (1993) and Chiou et al (1995) report a Nu number proportionality of Re 0.8 Pr 0.4 , while Copetti et al (2004) reports a Nu number proportionality of Re 1.1 Pr 0.4 . Moreover, in a singlephase heat transfer study by Brognaux et al (1997) it was concluded that the Prandtl number exponent should be near 0.56-0.57 as opposed to 0.4 as reported by many authors.…”

“…Considerable information on single-phase heat transfer in small/micro passages was included in a review by Rosa et al [11]. Recently, attention has moved towards micro-pin-fin structures [12][13][14][15][16][17][18][19]. Developments in processing techniques such as electron beam, microdeformation, and selective laser melting allow complex microsized geometries to be fabricated in a wide range of conductive materials.…”
