The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 2.3 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.2 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00037 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.6 SJR: 0.433 SNIP: 0.593 CiteScore™:: 4.3 H-Index: 35

RÉSUMÉ

Shell-and-tube heat exchangers (STHXs) have been widely used in many industrial processes. In the present paper, shell-side flow and heat transfer characteristics of shell-and-tube heat exchanger with continuous helical baffles (CH-STHX) is experimentally studied. Correlations for heat transfer and pressure drop, which are estimated by the Nusselt number and the friction factor, are fitted by experimental data for thermal design. The computational fluid dynamic (CFD) method is also used to compare the shell-side heat transfer and flow performance of the CH-STHX, STHX with combined helical baffles (CMH-STHX), and STHX with discontinuous helical baffles (DCH-STHX). The numerical results show that, for the same Reynolds number, the shell-side Nusselt numbers of the CMH-STHX and CH-STHX are ∼37.6% and ∼78.2% higher than that of the DCH-STHX, and shell-side friction factors of the CMH-STHX and CH-STHX are ∼104.1% and ∼177.0% higher than that of the DCH-STHX. Reasonable maximal velocity ratio design can make the CMH-STHX and DCH-STHX have higher heat transfer coefficients than the CH-STHX for the same mass flow rate in the shell side.
