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

This article reviews recent experimental work conducted at the Laboratoire de Combustion et Systemes Reactifs (LCSR), Orleans, France, on single droplet breakup and vaporization. Emphasis is essentially put on high pressure and turbulence effects. The experimental facilities developed and the diagnostics used are first presented. Droplet breakup studies are conducted with cryogenic and noncryogenic droplets subjected to aerodynamic shear forces under high-pressure conditions. The transition criteria between droplet breakup regimes, characteristic breakup times, and secondary droplet distributions are obtained for uniquely low values of the density ratio between liquid and gas phases and systematically varied values of droplet Weber and Reynolds numbers. Combined effects of high pressure and temperature on droplet vaporization are also systematically explored. The variation patterns of average vaporization rates with reduced pressure and temperature are conclusively established and compared to estimates from the quasi-steady model. The influence of turbulence on droplet vaporization rates is explored in detail. It is demonstrated that droplet vaporization rates increase significantly with turbulent Reynolds number, even when the droplet size is smaller than the turbulence integral length scale. Comprehensive correlations are established to take into account these various effects. Suggestions are made for ways of including these correlations as submodels into spray combustion numerical prediction codes and for future work to further improve them.
