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: 1.2 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: 1.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 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: 0.00095 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: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

ABSTRACT

We investigate by numerical simulation a highly unsteady cavitating flow of ISO 4113 test fuel in the valve chamber of a Diesel common rail injection system. Two-phase modeling is based on a single-fluid approach and a homogeneous mixture model. A fully compressible flow solver, taking into account the compressibility of liquid and liquid–vapor mixture, is employed. Computational results for two similar designs are presented. We discuss the cavity dynamics and reverse flow development in the discharge throttles for a pressure drop of approximately 2000 bar and choked flow conditions. The focus of this study is placed on inertia-driven effects and formation of collapse-induced pressure peaks, which allows us to apply an inviscid flow model. Our contribution assesses the erosion risk by monitoring maximum instantaneous wall pressures and employing a collapse detector algorithm for the identification of implosions of isolated vapor clouds. High-speed liquid jet discharging from the throttle, accompanied by supercavitation and reverse motion in the throttle, is predicted by the numerical simulation. Collapse pressures higher than 1 GPa are observed near material surfaces, resulting in high surface loads which can eventually lead to material erosion.
