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

ABSTRACT

An experimental investigation of mean and turbulent flow fields resulting due to the interaction of subsonic, axisymmetric, hot and cold air jets in coaxial configuration has been reported. The basic characteristics of turbulent jets such as axial spread, radial growth and centre line decay of flow variables were altered remarkably with addition of heat. When the Gaussian shape of the normalized mean velocity distribution across the jet was not significantly affected by the heating, the local values of mean axial velocity were different for different levels of heat addition. The increase in entrainment in the initial region is due to the combined effect of mechanisms such as a large amount of small-scale vorticity, strong acceleration of jet due to density difference and larger radial expansion Based on the experimental data, a correlation was developed to predict the variation in entrainment ratio for different heating levels. The spatial variation of turbulent Prandtl number, a parameter that compares the relative rates of turbulent momentum and turbulent heat transfer, is found to be dependent on temperature ratio.
