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

摘要

The paper presents results of an experimental investigation of heat transfer and friction in a high-aspect-ratio rectangular duct with repeated rectangular cross-section ribs on one broad wall in v-discrete and discontinuous patterns at different angles. The ribs have been arranged in both v-up and v-down patterns. The flow and thermal boundary conditions correspond closely to those of solar air heater ducts. Over the range of the Reynolds number studied, the Stanton number and friction factor values for the roughened ducts are 1.56−2.21 and 1.65−2.93 times of the values for the smooth duct, respectively. Thermal performance comparison of different rib patterns, based on equal pumping power for roughened and smooth ducts, shows that 60° v-discrete ribs with a relative roughness length of 6 gives 4−18%, 14−27%, and about 3−5% better performance than the 45° v-discrete ribs, discontinuous ribs, and 60° discrete ribs with a relative roughness length of 3, respectively. The performance of the v-down arrangement of ribs is better than v-up arrangement for all cases studied. The friction factor and heat-transfer coefficient correlations have been developed for the most preferred type of roughness.
