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

Coating is the process of covering solid particles' surfaces with a homogeneous layer of a coating agent comprising one or multiple components. For processes carried out in fluidized beds, coating is achieved by spraying the coating agent on the particles in suspension. The aim of the present work was to study the atomization of molten materials prior to their application to powder coating in fluidized beds. Several external mixing binary nozzles were used for the atomization of a stearic−palmitic acid mixture and different polyethylene glycol grades (1000, 1500, 2050, 4000, and 6000) at different temperatures (60°C, 70°C, 80°C, and 90°C). The droplet size distributions, from which experimental mean droplet sizes were calculated, were measured by the laser diffraction technique. Subsequently, mean droplet sizes were satisfactorily modeled using different correlations reported in the literature. For a given nozzle, it was found that some fitting parameters were constant for all the polyethylene glycol grades, whereas others showed a dependency with the material viscosity. This latter was the property with the highest variability over the experimental domain. The fitted models did not provide a good prediction of the experimental data corresponding to different nozzle configurations or molten materials; therefore, new fittings were performed. This fact highlights the difficulty in obtaining models at least applicable to the atomization of molten materials.
