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 aim of this paper is to analyze theoretically the performance of newly designed double porous layered axially undefined journal bearing lubricated with ferrofluid considering combined effects of anisotropic permeability of the double layered porous facing, slip velocity at the interface of the porous matrix and film region, and squeeze velocity. Ferrofluid [1] is used because it generates body force µ0 (M · ∇)H in the presence of magnetic field H; µ0, M are free space permeability and magnetization vector respectively. Porous layer is because of having self lubricating property of the bearing. Expressions are obtained for dimensionless pressure and load carrying capacity for this newly designed journal bearing. The values of dimensionless load capacity are computed using ferrofluid as lubricant and compared it with the values which are obtained using conventional lubricant (that is, without using ferrofluid). From the results, we say that with using ferrofluid as lubricant, the dimensionless load capacity increase up to 206.86 %. Thus, with the use of ferrofluid as lubricant, it is found that the bearing performance is much better than that of a conventionally lubricated bearing.
