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

Numerical simulation of low Reynolds turbulent free jet issuing from circular nozzles with and without tabs, using the Shear Stress Transport (SST) k−ω model has been carried out. First, the numerical model validation has been performed by comparing computed results with Particle Image Velocimetry (PIV) measurements for the circular nozzle without tabs. The obtained results show reasonable agreement, principally for parameters such as centerline longitudinal velocity, longitudinal fluctuating velocity, and volumetric flow rate. Secondly, the tested numerical model has been applied for tabbed jet and results were compared with those of the circular jet without tabs. It is showed that the turbulent jet flow is modified by the presence of tabs. Also, it is found that the circular jet with tabs has better mixing performance compared to the circular jet without tabs. With these results, the tested numerical model can be considered as an efficient and costless mean for optimizing circular nozzle geometry for Heating Ventilation Air Conditioning (HVAC) applications.
