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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

SINOPSIS

The objective of this paper is to show the effect of a solid (or nonvaporizing) dipersed phase on the turbulent structures of an impinging jet. Direct numerical simulation (DNS) has been carried out to fully describe the turbulence evolution from the jet destabilization up to the breakup of the structures. A Lagrangian solver has been coupled to the DNS code to describe precisely the interactions between the particles and the gas. Two kinds of particles have been considered: (1) incident particles that are embedded in the jet at the injection level. These particles modify strongly the turbulence characteristics and increase heat transfer from the jet; (2) when incident particles are impacting on the wall, very small ejecta (particles of carbon) may be emitted and, in this case, heat fluxes decrease because of strong turbulent mixing close to the wall. Creation of small swirling structures as well as core of recirculation close to the wall could be detected thanks to numerical visualization of nonstationary flows.
