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

This experimental study concerns the impact of droplets of yield-stress materials onto flat surfaces. A commercial vaseline was selected to undertake the study. This fluid exhibits a measurable yield stress and permits the development of a droplet. Its basic characteristics (density, static surface tension) were determined and its rheology characterized. The viscosity data have been modeled using a Cross model, modified to build in a yield stress.
Droplets of the fluid were impacted upon a dry, smooth Plexiglas surface. Their deformations after impact were visualized using a high-speed video camera operating at acquisition rates of 9000 or 13,500 frames a second.
For low-impact velocities, the droplets first behave like deformable solids. Then a long-time-scale creeping flow takes place. For high-impact velocities, each droplet is seen to start spreading onto the surface. As it spreads, its velocity decreases and the stresses decrease until they eventually fall below their yield value. When the limit is reached, the spreading stops suddenly. Then, surface tension is not strong enough to overcome the yield stress and the recoil of the droplet is prevented.
Consequently, the final shape of the droplet depends on when the yield-stress limit is reached in the spreading phase. When increasing the impact velocity, the maximum spreading increases and the flow stops sooner.
