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

SINOPSIS

A micromachined ultrasonic droplet generator is demonstrated for atomization of liquids for fuel processing. The device comprises a bulk ceramic piezoelectric transducer for ultrasound generation, a reservoir for the fuel, and a silicon micromachined array of liquid horn structures as the ejection nozzles. Since one piezoelectric actuator can drive multiple ejectors of a single array, the array size can be scaled to meet flow rate requirements for higher power applications. Furthermore, due to the planar configuration of the ejector array, it is ideally suited for integration with the planar design of fuel cells. Simulations of the harmonic response of the atomizer confirm that operation at cavity resonances and the use of acoustic wave focusing yield low power consumption. Device operation is demonstrated through atomization of water and methanol from 4.5 to 16 μm diameter orifices at multiple frequencies between 0.5 and 2.5 MHz. The results of high-spatial-resolution visualization experiments combined with a scaling analysis of the fluid mechanics provide a basic understanding of the physics governing the ejection process and allow for a comparison of device operation with different fuels. A high degree of control of the atomization process and highly uniform atomization at low flow rates are achieved with a device that is extremely simple to fabricate, assemble, and operate.
