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

This paper deals with measurements performed with infrared (IR) thermography to measure wall convective heat fluxes in complex fluid flows. Convective heat fluxes are usually measured by means of a thermal sensor, described by a suitable heat transfer model, where transducers measure temperatures. If compared to standard transducers, the infrared camera appears to be very valuable because it is non-intrusive, has a high sensitivity (down to 20 mK), has a low response time (down to 20 μs); the camera is fully two-dimensional (from 80k up to 1M pixels, at 50 Hz) so, allowing for a better evaluation of errors due to radiation and tangential conduction within the sensor. By correctly choosing the measuring sensor, IR thermography can be exploited to resolve convective heat flux maps with both steady and transient techniques. The article presents a number of convective heat transfer measurements in complex fluid flows, performed with IR thermography by the author and his co-workers, which range from very low-speed flows (natural convection) to very high-speed ones (hypersonic regime).
