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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RÉSUMÉ

The use of laser Doppler anemometry (LDA) to investigate the non-stationary signal from an oscillating bubble produced by an underwater spark is presented. The major benefit of using LDA to measure the flow over traditional techniques such as hydrophones is that the method is non-intrusive and therefore does not influence the flow. The non-stationary Doppler signal is analyzed in a novel way using wavelets to produce the instantaneous velocity of the flow at the measurement point and hence pressure. This can be used to obtain the bubble oscillation period, maximum radius and energy. The form of the energy transfer from the circuit to the bubble in terms of the spark gap width is found to be non-linear and an empirical relationship for the decay of the bubble peak pressure with distance from the bubble center is obtained.
