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

A numerical study is performed to investigate two-dimensional, incompressible thermal-fluid flow in a confined channel in the presence of dual laminar jet impingement. The governing equations are discretized by means of a finite-difference technique and numerically solved to determine the velocity vector and fluid temperature distributions under the appropriate boundary conditions. The Reynolds number (Re), the velocity ratio (N) at the nozzle tip, the angle (θ) of an inclined upper wall surface, and the dimensionless nozzle height (H) from the heated wall are varied to determine their effects on both the formation of jet flows and the heat transfer along the flat plate impinged by the dual jet. It is found from the study that: (i) the isotherms and the velocity distribution, particularly in the stagnation zone, are substantially affected by the velocity ratio, (ii) heat-transfer performance along the heated plate is intensified by increasing the Reynolds number and by decreasing the nozzle height, and (iii) the effect of θ becomes larger in the downstream region.
