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: 0.6 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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

ABSTRAKT

An optimization at the lower off-design mass-flow range of the radial-inflow variable geometry turbine is required for future turbine applications. One of these applications is using this type of turbine as the throttling apparatus for a spark ignition engine to recover energy which is wasted by the conventional throttle. A wide operating mass-flow range with significant turbine efficiency is needed for these applications. The stator-to-rotor interaction is optimized of a standard radial-inflow turbine by changing the variable-vane-angle stator vane ring geometry. The flow at the conventional and a new design stator vane ring is analyzed using particle image velocimetry (PIV) with the intention of using the results to substantiate the increase of performance of the new turbine with new designed stator vane ring and for the admittance of computational fluid dynamic simulations. A PIV experimental setup is built to visualize the jet flow between and directly downstream the stator vanes. Two-dimensional steady-state jet-flow characteristics are mapped at several stator vane positions. Two series of fixed positioned stator vane rings are fabricated by rapid prototyping which represent the original and new variable-vane-angle stators. The flow characteristics of both series of vane rings are compared.
