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

SINOPSIS

A vortex tube is a device that separates an incoming compressed gas into two streams, one having a lower temperature and the other having a higher temperature than the incoming gas. An experimental study on the vortex tubes having a different curvature was reported here with air as the working medium.With the increase in inlet pressure, the temperature separation and cooling capacity increased. Isentropic efficiency and cooling capacity as two performance parameters for a vortex tube were reported here. The U-shaped tube had better performance in terms of temperature separation and cooling capacity for the higher cold mass fraction at all inlet pressures. When compared to results reported by others, the use of the rectangular inlet instead of the circular inlet lead to better performance of the vortex tube. The plot of isentropic efficiency with respect to the cold mass fraction was flatter at low inlet pressure. Irrespective of the inlet pressure, the maximum isentropic efficiency for all types of tubes lies between 0.20 and 0.33. The flow visualization using dye was done on three different types of Perspex® tubes at low pressure. The curved and U-shaped tube had the larger number density of helices near the inlet, which resulted in higher temperature separation and subsequently cooling capacity in a vortex tube.
