Abstract: In this study, a fuzzy logic model is proposed for the prediction of heat transfer as well as pressure drop along a helically perforated twisted tape in circular heat exchanger tube. Significance of helical perforated twisted tape parameters like diameter ratio, relative pitch ratio, perforation index and Reynolds number on the heat transfer and pressure drop in circular heat exchanger tube has been analyzed. Also, fuzzy logic relevant to air flow, heat transfer and pressure drop is generated for different sets of helical perforated twisted tape and flow parameters. The maximum error of fuzzy logic technique as compared with experimental data was found to be 1.05%. |
Keywords and phrases: fuzzy logic, heat transfer, pressure drop, Reynolds number.
