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

In order to solve the incompatibility between the diameter and the depth of borehole in high-pressure jet drilling, a novel nozzle that incorporates both advantages of a round straight jet and a swirling jet was designed. The flow field structure and rock breakage characteristics were investigated in experiments for these three nozzles, which generate round straight jet, swirling jet, and straight−swirling integrated jet respectively. Meanwhile, three-dimensional flow fields were simulated for these three jets in terms of a k-ε turbulent model. The results reveal that the straight−swirling integrated jet has features of both a round straight jet and a swirling jet, inheriting both the deep penetration of a round straight jet and the large impact area of a swirling jet, but with larger hole diameter than the round straight jet and greater depth than the swirling jet. The axial velocity of the integrated jet has no potential core compared with a round straight jet, but is much higher than a swirling jet without a protrusion left at the bottom of the drilling hole. The tangential velocity of the integrated jet showing a radial M-shape distribution can form a large aperture, and the symmetrical velocity distribution presents obvious crossflow layers that are helpful for removal of rock fragments from the matrix. The numerical simulation results agree well with the actual flowing structure and the rock breakage features. A hole with expected characteristics can be drilled through adjusting nozzle structural parameters.
