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: 0.6 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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

RESUMO

The nasal cavity is an example of a complex three-dimensional flow channel with limited accessibility for internal measurements. Clinical CT and MRT data together with CAD tools offer ways to create solid models of the cavity. Yet, due to limited transparency and the need of refractive index matching when using liquid as working fluid it remains difficult to collect velocity data from the cavity. In order to overcome this difficulty, we present an approach that uses segmented models. Different from other reported velocity measurements in models of the nasal cavity they allow operation on a 1:1 scale with air. PIV is applied straightforwardly at the cutting planes yielding velocity distribution and flow rate. Results are provided for two models representing the geometry of two individual nasal cavities at peak flow of 1 liter/s together with a flow rate/pressure characterization. It is concluded that the use of segmented models is an encouraging means for applying PIV to flow in complex 3D passages like nasal airways.
