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

RÉSUMÉ

Low specific speed centrifugal pumps have been extensively applied in petroleum, petro-chemical, and other industrial sectors to transport liquids in a variety of viscosity. Their transient performance during starting and stopping processes can be important for their operational reliability; however, this performance has not been tackled under pumping highly viscous oils conditions so far. In the article, the transient turbulent flows in a low specific speed centrifugal pump are simulated with CFD code in starting and stopping periods for three liquids. The effects of viscosity on instant performance parameters, head-flow rate curves, instant internal flow variables, and flow structures in the impeller and volute are demonstrated. The parameter synchronization characteristic, hysteresis phenomenon in head-flow rate curves, and pump affinity law modification are addressed. It is turn out that a highly viscous liquid can respond to the pump speed change more quick than water, but is subject to a more significant overshoot in the shaft-power curve; thus, a liquid with higher viscosity than water potentially can reduce the operational reliability of a low specific speed centrifugal pump during the starting period.
