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

ABSTRAKT

High-pressure-driven "twin-jet sprays" were studied in connection with development work for new injectors for combustion engines. For this purpose, a test rig was set up that allowed two high-pressure liquid jets to be produced that could collide at a pre-given distance and impingement angle. From the crossing regions of the investigated twin jets, very fine sprays emerged. Their properties were investigated for different orifice diameters, different impingement angles, and different jet velocities. The experimental results obtained with the test rig are summarized in this paper. They are compared with corresponding theoretical results obtained using theories of spray formation by twin jets available in the literature. The agreement regarding the measured particle size turned out to be poor for high supply pressures and it was therefore decided to develop an extended theory to describe the experimentally obtained data. The resultant theory is summarized and some predicted results are compared with corresponding experimental data. Good agreement was achieved between the authors' experimental and corresponding theoretical results. Hence a theory resulted from this work for predicting the droplet size of twin-jet sprays at high pressure. The applicability of the theory at low pressure was also achieved by adding some experimental findings.
