Plate-fin heat exchangers and tube-fin heat exchangers with wavy surfaces are characterized by high compactness and excellent heat transfer performance [1]. Early data on geometries of wavy surfaces were presented by Kays and London [2]. Three sets of geometries were studied by using the air as working fluid. This paper presents a discussion on two recent pressure drop and heat transfer models introduced by Awad and Muzychka [3] and Asadi and Xie [4].

Awad and Muzychka [3] studied on thermal-hydraulic performance of an air-cooled compact heat exchanger with wavy surfaces. They developed a new model by combining the asymptotic behavior for the low Reynolds numbers and laminar boundary layer regions. They used this model for predicting friction factor (f) and Colburn factor (j) in a wide range of Reynolds numbers. They...
