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: 0.6 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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

ABSTRAKT

Atomization of a jet in air cross flow has numerous applications in industrial and natural systems. In this study, spray characteristics (i.e., droplet mean diameter, Sauter mean diameter, and volume flux distribution) generated from perpendicularly interacting air jet of 7.5-mm diameter and water jet of 0.8-mm diameter are characterized using a phase Doppler particle analyzer (PDPA) in a forward scattering mode. The investigation is done for seven momentum ratios (q), where the momentum ratios are varied by varying the jet flow rate while keeping air flow rate constant. The jet Weber number is calculated to be 42.56, which is constant for all the cases and falls under the multimode breakup regime. PDPA measurements are done at different spatial locations, 40 mm below the tip of the injector to avoid ligaments and to ensure stable droplets. From the experimental results, it is found that for all flow conditions, volume flux is maximum near the geometric center of the spray and decreases towards the edges indicating the solid cone structure of the spray. The volume flux also increases with increase in q. The maximum of mean droplet diameter (D10) and Sauter mean diameter (SMD or D32) is found at the geometric center of the spray in the x direction, whereas in the y direction the maximum D10 and D32 are shifted towards the windward side of the jet. The diameter-velocity correlation is negative at the center of the spray and positive at the edges for both x and y directions. The correlation model for volume flux is found to be in accordance with the experimental data, while a few outliers are found in the diameter model due to the presence of large droplets that skew the data.
