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

ABSTRACT

The present study was conducted to investigate heat transfer enhancement from the endwall of a protruding circular cylinder by addition of a winglet vortex generator pair. A steady-state liquid crystal thermography technique was employed. The vortex generator pair is installed upstream of a cylinder placed either in counter flow inward or counter flow outward orientation. The vortex generator installed in the counter flow inward orientation presented the best heat transfer. The effects of the vortex generator attack angle on the junction wall heat transfer are also investigated and the 45° yaw angle with respect to the streamwise direction provided higher thermal performance. The position of the vortex generator with respect to the cylindrical obstacle is swapped in the streamwise and spanwise directions to find out the appropriate location of the vortex generator regarding enhancement of endwall heat transfer. The results indicated that the effect of the vortex generator in enhancing the endwall heat transfer is prominent in the spanwise direction rather than in the streamwise direction. Up to 25% heat transfer enhancement has been found with a pressure drop penalty of 4.8%, thus giving high thermal performance.
