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

SINOPSIS

The hydrodynamic problem of a two-dimensional model of seafloor mining tool entering still water vertically with free fall motion is analyzed based on the velocity potential theory. Simulations are performed using Navier−Stokes numerical method in conjunction with an interface-capturing VOF method employing CFD code Fluent, the time histories of velocity and pressure during the impact process are obtained. Residual air entrained between the bottom of mining tool and free water surface is observed, influence which exerts on impact is discussed, the concept of impact added mass is presented to express the coupled function between air-rigid body-water during water entry process. Two dimensionless ratios are determined which the drop simulations should comply with to simulate an average slam: drop height ratio and mass ratio. The relationships between dimensionless ratios and several important parameters derived from simulation results are discussed. The numerical results can provide an important principle for free fall water entry experiments.
