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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RÉSUMÉ

Prior models for porous inert medium (PIM) burners have not been able to accurately predict burning speeds, CO emissions, and NOx emissions. All prior models for these burners have assumed laminar flow within the porous structure. However, there are reasons to believe that the flow within these burners is turbulent. Therefore, a turbulent PIM burner model has been developed. A one-equation k-ε. model is used to simulate the turbulent flow field. This model makes use of the fact that the pore size constrains the size of the largest turbulent eddies. Thus, the integral length scale, which is assumed to be a simple function of the pore size, is used to determine e. It is also assumed that the dominant effect of turbulence is enhancement of the transport properties. The increased transport properties result in broader flame zones, decreased gas temperatures, and increased burning rates. The decreased gas temperature results in decreased NOx emissions. The resulting predictions of the CO emissions are also improved.
