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

RÉSUMÉ

This paper investigates the interaction between the impact of a liquid droplet and a moving liquid film in which a shearing airflow is present above the liquid film. Visualization of droplet trajectory, deformation, and impact outcome are provided. Droplet diameters used in this study range from 2.4 to 4.8 mm, water film thicknesses are between 0.2 and 1.7 mm, and the shearing air velocity within the rectangular duct is between 4.5 and 15 m/s. Two high-speed cameras are used to track the droplet and visualize the film surface. A laser focus displacement meter is used to obtain the instantaneous and average film height. By analyzing the acquired images, along with the film height, different regimes for both droplet deformations in shearing air and impact outcomes are observed. A regime map is produced relating the air, film, and droplet properties with the outcomes of the interaction between the droplet and the moving water film. The shearing air has an important effect on the interaction process before the impact by deforming the droplet and confining the film thickness; it also influences the impact process during and after the impact. Where the droplets retain their spherical shape before impact (low shearing air velocity), the transition between splash and deposition agree with published results obtained for droplet impact onto static films. The waviness of the film has no clear effect on the impact outcomes but does have an important effect on the way splash occurs with a big difference in the size of secondary droplets.
