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

In the cooling process of high-temperature calcined petroleum coke (CPC) inside a cooling water jacket, some problems such as uneven heat transfer, difficult heat conduction, and easy oxidation seriously affect the quality of CPC. Based on the computational fluid dynamics, this paper performed heat transfer analysis and numerical simulation for the cooling water jacket on both the water side and coke side, studied the evolutions of the internal temperature field, and obtained the nonuniform temperature field. Meanwhile, in order to enhance the heat transfer performance of the cooling water jacket, one modified measure was put forward by installing heat exchange tubes inside the cooling water jacket. The simulation results manifested that the modified measure of the cooling water jacket can enhance heat transfer performance significantly. Compared with the initial model, the outlet average temperature of CPC reduces by 293.89 K, and the cooling efficiency of the cooling water jacket enhances by 30.84%. Additionally, the temperature uniformity coefficient on the outlet cross section increases by 13.40%, which demonstrates that the modified structure has superior relative heat transfer performance.
