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: 1.2 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: 0.3 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: 0.00095 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: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

ABSTRACT

Measurements of the turbulence modulation term, u′gi u′pi, between the carrier and dispersed phases from experimental data were performed by a phase Doppler particle analyzer (PDPA) system. The cross-correlation function between phases, u′gi(t) u′pi(t + τ), was first determined from the measured raw data, which involved real-time information about velocities and associated drop sizes. The time delay, τ, was selected based on the flow characteristic time. The velocity of 2-μm drops was taken as that of the carrier phase. The cross-correlation functions for 10-μm, 20-μm, and 30-μm drops were then calculated from the raw data for each size range. The value of the cross-correlation function at τ = 0, that is, the turbulence modulation term, was obtained based on the symmetric property of this function and interpolation of the data. Results show that the turbulence modulation term can be expressed as functions of drop relaxation time, τp, turbulence kinetic energies of both phases, κ and κp, Reynolds stress u′g v′g, and velocity correlation of the drop phase, u′p v′p, instead of the formulation suggested by Pourahmadi and Humphrey [5] as well as by Chen and Wood [3, 4], which considered τp and κ only. It is suggested that the modeling of spray flow requires a more complete formulation based on the experimental data shown in this article.
