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: 1.7 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: 1.4 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: 0.00072 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: 0.43 SJR: 0.318 SNIP: 0.568 CiteScore™:: 3.5 H-Index: 28

RESUMO

In the geological carbon dioxide (CO2) capture storage (CCS), the dissolution of CO2 into brine formation increases the storage security against potential leakage due to buoyancy. The density-driven natural convection between the brine and CO2 solution plays an important role in the process of dissolution in geological formations. We visualized convective mixing of miscible fluids due to the density difference in a packed bed of particles by means of an X-ray computer tomography scanning a system where the lower light layer is four times thicker than the upper dense layer. On the interface, the fingering structure associated with the Rayleigh-Taylor instability is formed. For a packed bed with particles of equal diameter, the structure of the formed fingers tends to be fine and the number density of the fingers increases with the Rayleigh number Ra. However, even for fine particles, although Ra is low, a fine fingering structure is formed. The fingers that merge with neighboring fingers to form a continuous structure extend with time and coalesce with the neighboring fingers, thereby increasing their diameter and reducing their number density. The mechanical dispersion has a strong impact on the broadening of the finger diameters and the merging process with neighboring fingers. The Sherwood number, a dimension-less measure of convective flux, is correlated with Ra with a power of 0.86. The Sherwood number for the three-dimensional Rayleigh-Taylor instability is a few times higher than those evaluated for the Rayleigh-Benard convection.
