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: 1.5 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 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: 0.00017 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: 0.279 SNIP: 0.544 CiteScore™:: 2.5 H-Index: 22

Краткое описание

A numerical investigation was performed to determine the effect of the lateral angle injection on film cooling effectiveness over a turbine blade. The rows are located in the vicinity of the stagnation line. One row is located on the suction side and the other one is on the pressure side. The predicted pressure field for various blowing ratios (M = 0.5, 1.1, and 1.5) is compared to available experimental results at the design condition. Moreover, the effect of three lateral angles 30, 45, and 60 deg at three blowing rates is investigated by analyzing the results of both laterally averaged and area-averaged values of adiabatic film cooling effectiveness. The outcomes of the numerical results indicate that the thermal protection of the blade can be strongly influenced by the lateral angle. The coolant structure flow is characterized by a dominant single asymmetric vortex on both sides. Lateral injection at angle γ = 60 deg significantly improves film cooling effectiveness. From γ = 30 to 45 deg, overall, no appreciable improvement could be noted in cooling performance except for the lower blowing ratio M = 0.5. At suction side, the increase of blowing ratio has an adverse effect on the blade thermal protection.
