Journal of Enhanced heat transfer , 18 (3): 191 207 (2011) MODELS FOR PRESSURE drop AND HEATTRANSFER IN AIR COOLED compact wavy FINHEAT EXCHANGERSM. M. Awad & Y. S. MuzychkaFaculty of Engineering and Applied Science, Memorial University of Newfoundland, St. John s,Newfoundland, Canada, A1B 3X5 Address all correspondence to M. M. Awad E-mail: detailed review and analysis of the thermal-hydrodynamic characteristics in air-cooled compact wavy fin heat ex-changers is presented. New MODELS are proposed which simplify the prediction of the Fanning friction factorfand theColburnjfactor. These new MODELS are developed by combining the asymptotic behavior for the low Reynolds numberand laminar boundary layer regions. In these two regions, the MODELS are developed by taking into account the geomet-ric variables such as: fin height (H), fin spacing (S), wave amplitude (A), fin wavelength ( ), Reynolds number (Re),and Prandtl number (Pr).
