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: 0.7 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: 0.7 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: 0.1 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: 0.00016 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: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

RESUMO

In this article, we review several inviscid, helical solutions that are developed in the context of cyclonic, swirl-driven combustors. Specifically, the survey focuses on three solutions: an exact inviscid solution, a heuristic model for swirl velocities, and a compressible vortex model derived from a modified form of the Bragg-Hawthorne equation. As part of this endeavor, an overview of the derivations and assumptions is provided. The structures of the resulting solutions are then contrasted by comparing their velocity fields. In all cases the outer region of the helical motion is characterized by the presence of a free, irrotational vortex. The key difference between the three models presented here originates from the manner by which their core regions are treated. In the exact inviscid solution, the swirl velocity remains singular as it approaches the centerline. Conversely, in the constant shear stress and compressible Bragg-Hawthorne models, the core singularity is suppressed. The resulting formulations provide the basis for ongoing efforts to increase the available toolsets for modeling-confined helical motions.
