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

ABSTRAKT

In the present research, by using the modification in some of geometrical parameters, the performance of viscous fluid centrifugal pumps has been improved. In other words, the effects of the inlet and outlet blade angles and passage width have been investigated. Numerical simulation of three-dimensional flow is carried out by an extended computational fluid dynamics (CFD) code. "k-ω SST", was chosen as the turbulence model and a high-resolution algorithm was used to solve the governing equations. The numerical results of impeller primary geometry have good compliance with the experimental ones. Through variations of these three characteristics, 18 different cases simultaneously were investigated. Analysis of the obtained results shows the efficiency and head of pump increase by reduction of the inlet blade angle and changes in the outlet blade angle and passage width. It is clear that with a 38.2 and 17.5 deg angle of the inlet and outlet blade, respectively, and a passage width of 21 mm, the head values and pump efficiency are optimized between the 18 cases.
