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

摘要

In this article, an incompressible Multiple-Relaxation-Time Lattice Boltzmann Equation (MRT-LBE) model for Large-Eddy Simulation (LES) of incompressible turbulent flows is considered. The implementation is discussed in the context of D2Q9 MRT-LBE model in conjunction with the Smagorinsky subgrid closure model. The MRT-LBE LES is applied to a two-dimensional driven cavity flow and double shear flow for studying the dynamics of flow structures. The combination of the LBE method with the subgrid model allows us to simulate the cavity flow up to a Reynolds number of 1000000. The MRT-LBE LES results are compared with (single-relaxation-time) SRT-LBE LES results and existing CFD simulations. Reasonable agreement between the presented numerical results and those of existing CFD simulations demonstrate that the MRT-LBE method is a potentially viable tool for LES of turbulence.
