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

RÉSUMÉ

Particle image velocimetry (PIV) measurements in polydisperse sprays have been investigated using Monte Carlo simulations. The objective of the study was to determine how using droplets with a wide size distribution for the "seed" particles in PIV measurements affects the mean velocity obtained from the cross-correlation of the image pairs. Simulations were conducted using a variety of droplet size distributions, including a uniform distribution (in which the probability density function is a constant value for all allowable droplet sizes), log-normal size distributions, Rosin-Rammler size distributions, and a size distribution determined experimentally using phase Doppler interferometry. It was found that polydispersity has a strong effect on the measured velocity field, with the measured mean velocities being weighted toward the velocities of the larger droplets. The estimated mean velocity resulting from the cross-correlation algorithm was found to be approximately equal to the mean velocity weighted by the droplet surface area for all of the size distributions investigated. Signal saturation in the images was also found to affect the cross-correlation of the image pairs and the resulting mean velocities.
