3-Dimensional Overall Performance Evaluation of Wavy Fin Tube heat Exchangers in Laminar Flow Regime

Abstract

The present day study is focused on two fin configurations, the wavy-fin in-line and the wavy-fin staggered. These fin configurations are numerically investigated in both staggered and in- coated tube layouts. Heat transfer and strain drop characteristics of the warmth exchanger are investigated for Reynolds numbers starting from two hundred to 2000. Model validation is carried out with the aid of evaluating the simulated case friction aspect (f) and Colburn thing (j) with the experimental facts of Bhuiyan et al. (2013). In this, have a look at the impact of geometrical parameters which includes fin pitch, longitudinal pitch and transverse pitch of tube spacing are studied. Results are supplied in the form of friction issue (f) and Colburn thing (j). This observe well-known shows that the waft distinction between plain and wavy fin has a profound have an impact on the warmth switch and go with the flow friction performance of these configurations when compared on the premise of tube layouts.
