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

要約

This study proposes a 1D model that describes the time variations of the spreading ratio for a non-Newtonian (shear-thinning) liquid drop impinging on dry solid surfaces. This model is based on the previous model developed for Newtonian liquids, where an energy balance approach with a cylindrical disk approximation was adopted and the dissipation mechanism near the contact line was taken into account. The present model showed good predictions for the spreading behavior, and accordingly the maximum spreading ratios were predicted with 97% of the data within ±10% accuracy. Also, the model predictions of the receding behavior for a low-viscosity drop impinging on a hydrophobic surface were in good agreement with the experiments. However, the discrepancy in the receding behavior became larger for the higher-viscosity drop impacting on a hydrophilic surface because the contact angle hysteresis appears more prominent. Based on this model, the time variations of the liquid viscosity for an impinging shear-thinning drop were simulated, and the effects of non-Newtonian liquid rheological parameters in the Cross model on the postimpingement behavior were also examined in detail. Consequently, it was found that the liquid viscosity in a high shear rate range dominates the spreading and receding behavior of a shear-thinning drop.
