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

SINOPSIS

Ambient winds may result in poor fan performance and exhaust plume recirculation of air-cooled condensers in a power plant. The adverse impacts of winds can be restrained by altering the flow patterns of the cooling air. A novel method which uses a flow guiding device installed below the platform is investigated in this paper. The physical and mathematical models for air-side fluid and heat flows in air-cooled condensers with a flow guiding device in a representative 2 × 600 MW direct dry cooling power plant are presented by introducing a radiator model to the fin-tube bundles. The flow rates, inlet air temperatures, and heat transfer rates of the air-cooled condensers as a whole and of the individual condenser cells are obtained and compared by using computational fluid dynamic (CFD) simulation. The results show that both the flow and heat transfer rates of the air-cooled condensers as a whole increase with the addition of the flow guiding device. For the upwind condenser cells that face the ambient winds, the flow and heat transfer rates vary widely owing to the flow field leading of the ambient winds by the flow guiding device. It is useful for the optimal design and operation of air-cooled condensers to effectively organize the flow fields of cooling air by various ways.
