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

We report for the first time the direct measurements of velocity vector profiles and strain rate distribution for both laminar and oscillatory flows in a baffled tube using the particle image velocimetry (PIV) technique. The PIV data reported here illustrate in detail the variations of the velocity vectors in a baffled region and provide a full insight into the fluid mechanical conditions generated by this type of flow configuration. The PIV results also show that the axial velocity components for oscillatory flow in a baffled tube are of comparable order to the radial velocity components, which quantitatively supports our previous studies. The measurements of strain rate distribution indicate that a pulsed baffled device can provide enhanced fluid mixing while maintaining a low strain rate, similar to that of a laminar flow. This finding is significant since it suggests that the pulsed baffled device could be beneficial for shear-sensitive bioprocesses where a low shear rate distribution is vitally important to cell cultures.
