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: 1.2 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: 0.3 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: 0.00095 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: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

ABSTRACT

The effect of adding CO2 to diesel fuel has been studied by several groups that used tailor-made injection systems to achieve notable low Sauter mean diameters (SMDs). In the present study, we use a real commercial fuel injection system and study the effect of the amount of dissolved CO2 on the resulting spray characteristics. In this case, when the mixture enters the injector and flows downstream through the variable cross-section passage toward the discharge orifice, partial nucleation of the dissolved gas is expected to occur at different locations along the duct, which transforms the mixture into tiny bubbles that grow fast downstream. When the mixture is driven out through the discharge orifice, these bubbles undergo a rapid flashing process that results in an intensive disintegration of the liquid bulk into small droplets. In the present study, we present an experimental study of the atomization process of diesel fuel containing dissolved CO2 that occurs in steady flow conditions. An extensive study was performed to map the effect of the CO2 content on the spray SMD and droplet distribution at different locations downstream the discharge orifice. It is concluded that the atomization of diesel fuel containing dissolved CO2, is significantly promoted by the flash-boiling phenomenon, which results in low SMD sprays, low D0.1 droplets, a faster breakup mechanism, and a more uniform droplet size distribution.
