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: 0.4 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: 0.1 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: 0.00005 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: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

Краткое описание

A numerical calculation model of heat transfer in the nozzle blades of high-temperature gas turbines with transpiration cooling has been developed. The model includes conjugate numerical calculation of convective heat transfer, heat transfer in the transpiration passages, and conductive heat transfer in the solid body of a blade. The results that characterize the structure of external flow, flow in the transpiration passages and in the blowing areas are being discussed. Distributions of the cooling efficiency, heat transfer rates, friction characteristics per turbine nozzle blade circuit are given. The possibility of obtaining an acceptable wall temperature level at a turbine-inlet temperature of 1800 K and cooling medium consumption is defined. It is noted that loss factor is 1.6% higher than in a standard blade.
