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

ABSTRAKT

Computational study of a turbulent evaporating spray was conducted using a Eulerian-Lagrangian hybrid model. Eulerian computation of the turbulent gas phase consists of the second-moment closure for the momentum equations and the heat-flux transport closure for the energy equation. Lagrangian computation of the droplet phase consists of an anisotropic droplet dispersion model for the motion of droplets in turbulent gas flow. Complete initial conditions from experimental measurements were used to investigate the effects of gas temperature fluctuation on droplet evaporation. Numerical results for the droplet phase obtained by including and excluding gas temperature fluctuation in the droplet Lagrangian equations were compared with each other, together with the experimental measurements. It was found that the inclusion of the gas temperature fluctuation has a strong effect on the vaporization of individual droplets, but has a negligible effect on global spray properties of ensemble-averaged droplet properties such as the velocity, diameter, and mass flux.
