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

Exact solutions to Navier − Stokes equations are rare due to its inherently nonlinear nature. Most of the known solutions are highly simplified and are obtained by eliminating certain terms. In case of three-dimensional transient Navier − Stokes equations, for all known solutions nonlinear part is zero. Nonlinear part of Navier − Stokes equations plays important role in various phenomena like convection and turbulent energy transfer. For some known axisymmetric and two-dimensional solutions nonlinear term is not zero but it is linearized. In this paper new type of solutions are obtained in which nonlinear part is not linearized and their nonlinearity is preserved. Solutions presented in this paper are believed to be first ever 3D nonlinear solutions of the Navier − Stokes equations for incompressible fluid. General solution of 2D Navier − Stokes equations for stream function homogeneous in space is obtained in the paper. These 2D solutions are used to enrich the obtained nonlinear 3D solutions. The sole purpose of this paper is to present new kinds of exact solutions, to help researchers trying to understand and explore physics of fluid motion.
