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: 1.7 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: 1.4 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: 0.6 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: 0.00072 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: 0.43 SJR: 0.318 SNIP: 0.568 CiteScore™:: 3.5 H-Index: 28

RESUMO

In this work, large-eddy simulations are performed using fire dynamic simulator to study the effect of wind and lip heights of a 0.3-m circular n-heptane pool fire. Wind velocities from 0.25 m/s to 2.3 m/s are considered to predict the flame tilt, mass burning rate, and various heat feedbacks. The results depict the maximum ratio of burning rate with wind to without wind as 1.36 and 1.26 of lip heights 0.025 m and 0.05 m, respectively. The radiation and convection feedback contributions range from 90.9% to 42.7% and from 9.9% to 57.3% for the lip height 0.025 m, respectively, and from 99.3% to 65.0% and from 0.7% to 35.0% for the lip heights 0.05 m, respectively. At relatively lower wind velocities, a larger lip height offers four times higher relative feedback (radiation to convection) contribution than a smaller lip height. Furthermore, at relatively higher wind velocities, the convection is predominant for smaller and radiation is predominant for larger lip heights.
