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

A computational model has been developed that can be used for the spray characterization of splash-plate atomizers. The computer model, called BLSpray, can accurately simulate the impingement of a liquid jet on the surface of a splash-plate nozzle, as well as the formation of the liquid film and subsequent droplets. To validate the model, simulation results were compared to experimental measurements for the film thickness and velocity distributions in a typical splash-plate nozzle. Close agreement between numerical results and measurements validated the model and its underlying assumptions. Correlations were developed between liquid film characteristics at the nozzle exit and the spray mean drop sizes. This was done by running many different numerical simulations on a typical splash-plate nozzle using the developed computer code. The correlations were obtained by performing a close inspection of the numerical results in order to extract all information regarding the liquid film and spray. The results of the developed code were combined with the correlations to get the spray drop size distribution in a more practical approach, with less computational time and effort. This capability, along with the program module developed for analyzing the output data, has turned the developed code into an efficient and practical tool in the design and characterization of splash-plate nozzles. The developed computer model can be used to predict the behavior of a flow into a nozzle at different operating conditions, and also as a tool in the design of new nozzles. This paper presents mathematical formulations, results of model validation, and the spray drop size distribution for a typical ALSTOM splash-plate nozzle. Also, the effect of some of the main parameters on the spray pattern, such as nozzle diameter, nozzle angle, and nozzle velocity, are investigated.
