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: 0.5 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: 0.8 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: 0.2 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: 0.00018 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: 0.11 SJR: 0.286 SNIP: 1.032 CiteScore™:: 1.6 H-Index: 10

摘要

Drop impact is important for numerous industrial processes. The recent progress in investigations of drop impact on heated solid surface covers the processes near and above the boiling temperature of the liquid. There is a gap in understanding of drop dynamics for the substrate temperature below the liquid boiling point. We conduct a detailed study of the interaction of the water drop of 10 μl impacting on a heated sapphire plate with a temperature varied within a range of 23–135°C. Characteristic stages of drop interaction with a substrate at various temperatures are identified, namely impact, spreading, rollback, one liquid column splashing, microdrops detachment, formation, stabilization, breakup, boiling, and evaporation. We show that the spreading time and maximal spreading diameter of the droplet are dominated by inertia and practically independent of the temperature. The influence of the temperature on viscosity dissipation, which limits the maximum spreading diameter, is not significant. However, the temperature rise leads to a considerable decrease of the liquid column contact diameter and to an increase of the liquid column height at the splashing stage. It is revealed that the contact line velocity at the rollback stage depends on temperature. Microdrop detachment from the liquid column is observed for a substrate temperature of 60–100°C. Beginning from the substrate temperature of 100°C, the liquid column height is decreased again. The most important observation is the drop breakup into several sessile microdrops just after the spreading for 135°C, which prevents the rollback and rebound. We show the possible importance of the Marangoni force for thin liquid film breakup and detect the presence of microbubbles, which is also potentially important for breakup.
