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

The transient performance of centrifugal pumps during transient operating periods, such as startup and stopping, has been drawn much attention in the past years due to the growing engineering needs. However, the prediction of the transient theoretical head of the impeller has not been satisfactorily established yet. In present study, a new generalized Euler equation for incompressible flow in turbomachinery is developed, which includes influences of the blade thickness and shape. Then, the proposed theoretical equation is compared with an existing one as well as the experimental data of two centrifugal volute pumps during startup periods. The results indicated that the proposed equation is feasible to estimate the transient theoretical head and the steady head rise. In addition, it is also found from both the theory and the experiments that the transient theoretical head is much higher than the steady one in the initial stage of startup period.
