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

A one-dimensional model is developed for the primary breakup of low-speed jets using the technique of tracking the wave growth on the liquid-gas interface. The continuity and momentum equations are reduced to one-dimensional (1-D) forms to calculate the growth of waves on the jet surface. A novel symmetrical initial condition is proposed to handle finite-length jets and complex disturbances. A fast Fourier transform (FFT) is used to capture the surface wave structure. The drop size distribution is calculated/row the Fourier series by assuming that the diameter of each drop is proportional to the wavelength of its corresponding wave and the mass associated with each drop size is proportional to its Fourier coefficient. A breakup criterion is proposed based on the growth of the surface area. This model is validated by comparing with linear theories and with measurements for low-speed jets. breakup characteristics, such as the drop size distribution and Sauter mean diameter (SMD), are studied for a range of injection velocities.
