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: 2.3 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: 1.8 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: 0.2 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: 0.00037 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: 0.6 SJR: 0.433 SNIP: 0.593 CiteScore™:: 4.3 H-Index: 35

要約

Mixed convective flow and heat transfer has been performed in a horizontal channel with built-in obstacles on one of the channel walls. The channel blockage is taken to be 20%. Two-dimensional time-dependent Navier-Stokes and energy equations are solved in a Cartesian coordinate system using higher order discretization. Time integration of the governing equations reveals the critical Reynolds number of unsteadiness to be between 525 and 550. The effect of Richardson number on unsteady flow at a fixed Reynolds number of 600, at which the flow is unsteady laminar, has been investigated. The Richardson number, the parameter of interest of the present study, is varied between −1.0 and 1.0. The fluid chosen for the present study is air whose Prandtl number is 0.7. The flow and heat transfer show good correlation, and intense mixing with complex flow structures has been observed downstream of the obstacle. The heat transfer is found to be higher for the positive buoyancy while no significant variation is observed for negative buoyancy or Richardson number.
