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

ABSTRAKT

The challenge of enhancing or optimizing the rate of heat transfer from heat exchangers is compounded by the lack of a simple and generally applicable approach for its analysis. Because the expressions for the log mean temperature difference (LMTD) correction factor, F, or those for heat exchanger effectiveness, e, are difficult to evaluate, the traditional analysis methods rely on heat exchanger specific charts. In addition to being applicable only to a particular heat exchanger, these charts are highly nonlinear and strongly dependent on the traditional parameters used for their evaluation. Expressed in terms of the nondimensional parameters P and R, the LMTD correction factor F charts are particularly difficult to read in the steep regions. These shortcomings also make the assessment of different heat transfer enhancement strategies tedious. In this study, an alternative approach for determining F in terms of two new nondimensional parameters, r and f, is presented. This new approach results in a single general algebraic equation for determining the LMTD correction factor of multipass shell and tube heat exchangers with any number of shell passes and an even number of tube passes per shell. This single expression can be used to devise and compare different enhancement strategies for shell and tube heat exchanger networks, including their arrangement, to optimize their rate of heat transfer. It is shown that the approach presented results in a novel expression for the determination of the number of shells needed to meet a predefined overall correction factor for multishell and tube heat exchangers.
