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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RESUMO

The present work investigates the effect of inlet pulsation on the transport process in two types of microchannel as circular and wavy microchannel. The flow was both thermally and hydrodynamically developing while the channel walls were kept at a uniform temperature. The inlet velocity varies sinusoidally in time for a range of dimensionless frequencies (St = 1, 5, 10) up to an amplitude of 0.8. The transient solution of two-dimensional Navier−Stokes equation was obtained using the SIMPLE algorithm with the momentum interpolation technique of Rhie and Chow. The simulations were performed in the laminar regime within the Reynolds number range between Re = 0.1 to 100 and Prandtl number 0.7 for both circular and wavy channels. The results of pulsating flow simulation have been analysed and compared with steady flow simulations. It is observed that the effect of pulsation in circular channel is significant only at low Reynolds number (Re ≤ 10) beyond which pulsation has little effect. On the contrary, wavy passage does not provide any significant heat transfer enhancement when the flow is steady, particularly at very low Reynolds number. Significant increase in heat transfer is observed when the flow is made unsteady. Further, non-dimensional pressure difference, friction factor and performance are analysed in this study.
