Abstract

The current study is focused on two fin configurations, the wavy-fin in-line and the wavy-fin staggered. These two fin configurations are numerically investigated in both staggered and in-lined tube layouts. Heat transfer and pressure drop characteristics of the heat exchanger are investigated for Reynolds numbers ranging from 200 to 2000. Model validation is carried out by comparing the simulated case friction factor (f) and Colburn factor (j) with the experimental data of Bhuiyan et al. [2013]. In this study the effect of geometrical parameters such as fin pitch, longitudinal pitch and transverse pitch of tube spacing are studied. Results are presented in the form of friction factor (f) and Colburn factor (j). This study reveals that the flow distinction between plain and wavy fin has a profound influence on the heat transfer and flow friction performance of these configurations when compared on the basis of tube layouts. For laminar flow conditions heat transfer and friction factor decrease with the increase of longitudinal and transverse pitches of tube spacing whereas they increase with fin pitches for both in-line and staggered configurations.
