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: 1.7 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: 1.4 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: 0.00072 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: 0.43 SJR: 0.318 SNIP: 0.568 CiteScore™:: 3.5 H-Index: 28

SINOPSIS

Ribs are often used in the mid-section of internal turbine blades to augment heat transfer from the blade wall to a coolant, but most research works are concerned only with continuous ribs attached to the side walls. In this paper, a turbulent flow and heat transfer of a rectangular passage with continuous and truncated ribs on opposite walls have been predicted numerically. Two types of ribs are studied: 90-deg ribs and 45-deg V-shaped ribs. The inlet Reynolds numbers range from 12,000 to 60,000. The complex three-dimensional turbulent flows inside the blade internal coolant passage and heat transfer between the rib-walls and side-walls are presented. The overall performances of six different ribbed passages are evaluated and compared. Numerical results show that the passage with truncated V-shaped ribs is very effective in improving the heat transfer performance with a low pressure drop.
