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

Transient performance of centrifugal pumps during transient operating periods, such as startup and stopping, has drawn more and more attentions recently due to the growing engineering needs. Up to now, the working fluid during startup period is limited to water only in those precious investigations. However, this is not always the case in practice; the study on solid-liquid two-phase flow is not reported. In this paper, the unsteady flows inside pump are numerically simulated using commercial code FLUENT during startup period when a low-specific-speed centrifugal pump is used to transport the pure water and the solid-liquid two-phase flow, respectively, and then the numerical results are compared with the experimental results of the pure water. In this numerical simulation of startup process, the variations of the rotational speed and flow rate with time obtained from experiment are fitted the function of time, and then are written into program by user defined function. The research results show that when the centrifugal pump is used to deliver the solid-liquid two-phase flow, there exist an overshoot in head during startup period, which is obvious higher than that of pure water. Moreover, the former obviously lags behind the latter to reach the stable operation state during startup period.
