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

摘要

In this work we review a few studies on the performance of the finite element approach in direct numerical simulations of liquid jet injection and droplet impact on dry surfaces. We consider the single-fluid formulation of the incompressible Navier-Stokes equations, discretize these equations on a fixed grid with the finite element method, and solve the resulting algebraic system with a multigrid technique. The finite element method allows a variational formulation of the capillary force that is implemented both with a volumetric approach and by using the Laplace-Beltrami operator. In order to study the injection of a liquid jet in a gas environment at low Reynolds numbers, we have implemented a multilevel volume of fluid (VOF) method because it can deal with strong topology changes in an automatic way. We have also considered a front-tracking algorithm to study the spreading of a droplet on a dry solid surface, because there is the need of a very precise positioning of the contact point, while there is no breaking or topology change. The results of several numerical experiments are presented and discussed for both cases.
