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: 1.7 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: 1.4 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: 0.6 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: 0.00072 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: 0.43 SJR: 0.318 SNIP: 0.568 CiteScore™:: 3.5 H-Index: 28

ABSTRAKT

This paper presents a methodology to predict the flow structure of cooling flows emanating from cylindrical film-cooling holes based on characteristic flow parameters. The dependence of the film-jet flow field on characteristic flow parameters, such as blowing ratio and density ratio, has been studied using a validated high-resolution computational fluid dynamics model of a film-cooled flat plate. For the film-jet flow structure, mathematical formulations have been developed based on physical and empirical considerations. Free coefficients in the proposed formulations have been adjusted using a least-square-fit method to match the results from the detailed flow simulations qualitatively and quantitatively. To establish a functional relationship between the least-square-fit coefficients and the film cooling parameters, models have been developed and optimized using analysis of variance. These models provide the capability to predict the proper choice of coefficients based on the film cooling parameters. The combination of coefficient models and mathematical formulations allows the prediction of the complete three-dimensional flow field of the film-jet-body in the vicinity of a film cooling ejection site.
