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

A new jet primary breakup model is proposed and applied to high-speed jets to predict the primary breakup characteristics. The liquid jet is modeled by discrete blobs. Initial conditions, such as jet diameter, injection velocity, and initial disturbances on the liquid jet, are provided by a nozzle flow model to reflect the effects of nozzle internal flow. The breakup characteristics of the jet are calculated by tracking the wave growth on the surface of each liquid blob using a one-dimensional Eulerian approach. Novel initial and periodic boundary conditions are applied to the computational domain that allow consideration of the unstable growth of complex initial disturbances. The surface structure of a blob is decomposed into a combination of waves with different wavelengths and is expressed in a Fourier series using a fast Fourier transform (FFT). The drops that are stripped from the surface are calculated from the surface wavelengths and amplitudes, as indicated by the Fourier coefficients. A multilayer drop-stripping model is proposed and multidimensional effects are included by reflecting the surface structure in the axial direction into the peripheral direction, as suggested by high-speed jet experiments that show that surface wavelengths are approximately isotropic. The new breakup model has been implemented in the multidimensional KIVA computational fluid dynamics (CFD) code to simulate spray atomization. The breakup model has been used to predict drop size, jet breakup length, and spray liquid penetration length. Comparisons with experimental data indicate that the new breakup model significantly improves spray predictions over standard atomization models that are based on linear jet stability theories.
