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

RÉSUMÉ

Spray formation by bi-component liquid flashing through a special-design injector has been studied. Special attention has been drawn to the processes inside the expansion chamber. The relevant processes, which include the pressure drop at the inlet orifice, nuclei formation, bubble growth inside the expansion chamber, and the pressure drop at the discharge orifice, have been analyzed by using a one-dimensional model approach. While the one-dimensional assumption is problematic, it enables simple analysis and yet provides realistic quantitative results.
It is postulated that in a well-designed expansion chamber, a prespecified void fraction has to be attained at the end of the expansion chamber. The latter is designed to yield this void fraction, subject to the thermodynamic conditions of the entering mixture and orifices geometries. The optimal volume of the expansion chamber is found to be...
It follows that the optimal volume of the expansion chamber depends strongly on the superheat degree, flow rate, and the cross-section area ratio between the inlet and discharge orifices.
