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: 0.6 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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

SINOPSIS

Hydrodynamic ram occurs when a projectile with sufficient kinetic energy impacts a fluid-filled tank and generates large pressure fluctuations within the tank, potentially contributing to the tank's failure. A common product of a hydrodynamic ram event is the transient spray, or liquid spurt, generated through the projectile's penetration orifice. Previous work described the resulting transient spray in distinct, sequential phases. Additional research noted cavities, for missiles entering water, as having distinct phases or features. Hence, experiments were constructed using two synchronized high-speed cameras to capture the interior cavity features through the tank's polycarbonate wall and the corresponding exterior transient spray phases. Research was conducted to relate the interior and exterior observations with 0.95 cm steel spheres ranging from 1,800, 1,495, to 1,200 m/s. Synchronized high-speed image pairs were collected within 0.2 μs of each other and proved crucial for confidently relating the interior cavity features to the exterior transient spray. Analyzing the synchronized image pairs yielded correlation of the pre-spurt, main spurt, and low-frequency pulsation transient spray phases to the respective cavity contraction, cavity separation, and cavity collapse features. Further delineation of the cavity phase into separate transitional phases provided insight for further hydrodynamic ram research to determine the physical relationship to the transient spray.
