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

SINOPSIS

In many engineering applications, the liquid films have to deal with sudden changes of the wall geometries in which they flow over. The present work concerns the study of the onset of the film atomization in corner geometries. Specifically, films with thickness in the range of 1 mm < hf < 2.5 mm and dimensionless scale parameters in the range of 2 < ε · Ref < 24, able to expand in a spanwise direction without side restrictions, are developed on a horizontal plate. The films approach a sharp corner of 90° at the end of the plate under the shearing action of an external airflow. The air velocity and the liquid flow rate in which the film atomization at the corner edge initiates are detected experimentally. The behavior of the mean film and its waves at the corner are studied under those conditions. Both the viscosity and the surface tension are varied to investigate the effect of the liquid properties on the onset of the film atomization. The experimental data obtained here are compared extensively with the atomization models found in the open literature. The comparison shows that the existing models are not able to predict the onset of atomization for the films of the current work. That happens mainly because the interfacial waves have been totally neglected from the models. Further theoretical development is required to successfully predict the initiation of the droplet generation in corner geometries.
