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

RÉSUMÉ

This study presents a numerical investigation of flow behavior of a turbulent impinging jet in semiconfined and confined rooms using computing code ANSYS computational fluid dynamics. The lobed grille is proposed as a novel air diffuser design in order to develop air distribution inside the room. A comparison of the different types of diffuser geometry (elliptical, rectangular, and lobed grids) is carried out. Different discharge heights (0.3 m, 0.6 m, and 0.9 m) are taken into account. The effect of jet designs on thermal confort is investigated also. The validation results show a good agreement with the experimental data found in the literature. The flow behavior and thermal characteristics of the three designs are presented. The results show that lobed grilles enhance the ventilation systems for both semiconfined and confined rooms.
