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: 1.3 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: 1.7 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: 0.7 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: 0.00023 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: 0.11 SJR: 0.244 SNIP: 0.521 CiteScore™:: 3.6 H-Index: 14

ABSTRAKT

In this study, the lattice Boltzmann method (LBM) has been applied for the first time to simulate incompressible flow in microporous media on nonuniform grids. The flow through porous media is simulated by including the porosity into the equilibrium distribution function and adding a force term to the evolution equation to account for the linear and nonlinear drag forces of the porous medium. Besides, nonuniform grids are adopted by using the explicit Taylor series expansion and least squares-based lattice Boltzmann method (TLLBM). The TLLBM is based on the standard LBM with an introduction of the Taylor series expansion and the least squares approach. The final equation is an explicit form and essentially has no restriction on mesh structure and lattice model. Since the Taylor series expansion is only employed in the spatial direction, the time accuracy of this method remains the same as the standard LBM. In order to validate the LBM code, at first, a lid-driven cavity flow in porous media is simulated and the obtained results are compared with the data existing in the literature. Then, the proposed method is applied to simulate a lid-driven cavity flow in microporous media for different Darcy and Knudsen numbers. The present results demonstrate the potential of the lattice Boltzmann algorithm on nonuniform grids for numerical simulation of fluid flow through porous media.
