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 main aim of this work was to assess the possible improvements on the thermal performances of a central body radiator converted in a convector by the addition of a convex electrically heated front cover. A three-dimensional steady-state numerical analysis was performed using computational fluid dynamics (CFD) simulations. The laminar flow regime was analyzed; a T-shaped finned central body temperature of 50°C and inlet air temperature of 19°C were imposed for all cases. The velocity and temperature distribution of air were evaluated at the inlet, central, and outlet sections for inactive cover and for four other different temperatures. Performances of the convector were investigated through energetic and exergetic analysis. For low cover temperatures a recirculation zone affects the plane-convex volume and turns into a localized inversion flow for increasing temperatures. Velocity and temperature profiles of air in the inlet, central, and outlet sections show that only the volume between the front cover and central body is significantly influenced by the temperature variation of the electrical resistance. A homogeneous temperature and velocity profile in the outlet section was achieved for thermal resistance temperatures of 50°C and 60°C.
