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

The volume of fluid (VOF) method is a useful tool for multiphase flow simulation. However, smallscale interfacial structures introduce significant computational challenges. One difficulty is determining interface curvature at low resolutions—a requirement in turbulent spray simulation. In this work we evaluate two finite particle schemes for computing curvature of poorly resolved interfaces in the context of VOF simulations. Curvature is computed from the convolved VOF in the first scheme and directly from the VOF in the second scheme. Both cell-centered and interface-centered calculations are considered in the first scheme, while only cell-centered calculations are considered in the second scheme. The methods are evaluated via the L2 and L error norms corresponding to the curvature of spheres. Results yield L2 errors less than 1% and L errors less than 3% for nearly all resolutions considered. Additionally, a hybrid implementation of the first scheme demonstrates greater accuracy than a contemporary variant of the height function method for resolutions relevant to spray simulations. The results suggest the finite particle method to be a valuable tool for computing interfacial curvature in flows with a poorly resolved dispersed phase.
