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: 1.5 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 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: 0.3 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: 0.00017 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: 0.28 SJR: 0.279 SNIP: 0.544 CiteScore™:: 2.5 H-Index: 22

SINOPSIS

This article deals with the interaction of twin inclined jets with an oncoming cross-flow. This configuration is widely present in industrial applications and depends on several parameters, such as the jets' height, the jet nozzles' spacing, the shape of the jet nozzles’ exit section, the velocity ratio and the temperature gradient. The gradient between the jets and the cross-flow temperatures is precisely the parameter we intend to handle in the present work, given its great environmental impact and as a response to technical constraints. The evaluation of this parameter is carried out numerically on the temperature distribution through the resolution of the Navier-Stokes equations by means of the finite volume method, the Reynolds Stress Model (RSM) second order turbulent model, and a non-uniform grid system. An experimental study is also carried and the corresponding data are depicted by means of the particle image velocimetry (PIV) technique and confronted to the numerical results, which gave good agreement. Such an evaluation gives insight about the cooling and heating processes resulting from the jets' interaction with the oncoming cross-flow. A good understanding of this process is likely to offer viable solutions to problems raised by this configuration such as the acid rain engendered by hot fumes or the deterioration of the combustors' walls by high-temperature jets.
