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: 1.7 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: 1.4 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: 0.6 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: 0.00072 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: 0.43 SJR: 0.318 SNIP: 0.568 CiteScore™:: 3.5 H-Index: 28

SINOPSIS

The present numerical study describes the phenomena of impingement cooling of a heated fl at surface by air and water mist-jet for mass loading fraction ƒ = 0.003−0.024 at Redhyd = 4500 and h/d = 5. A multiphase two-dimensional axisymmetric, incompressible and turbulent flow is considered in the present study. The results obtained using the standard k−ε, standard k−ω, RNG k−ε, realizable k−ε, and SST k−ω turbulence models were analyzed and discussed. The predictions of the local heat transfer coefficient show that the realizable k−ε turbulence model predicts heat transfer results better than other turbulence models. The comparative study was performed to select a suitable multiphase model among the volume of fluid, mixture, and Eulerian models. The Eulerian multiphase model predicts heat transfer from mist-jet impingement on a flat surface much better than the volume of fluid and mixture multiphase models. Normalized axial and radial velocities of the continuous and dispersed phase are presented to understand the fluid flow. The present numerical study also discusses turbulent kinetic energy near the nozzle exit and volume fraction over the heated flat surface.
