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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RESUMO

Results of experimental studies and numerical simulation of flow dynamics, heat transfer, character of boiling-up, and crisis phenomena development are presented for falling wavy films of cryogenic liquid (nitrogen) and water under the intensive transient heat generation. Step-wise and periodic pulsing heat release was supplied on the vertical plane constantan foil of the 25 µm thickness and 40 mm length. When loading thermal impulses of a high intensity, nitrogen film decay is determined by dynamic characteristics of propagation of the self-maintained front of liquid boiling-up and the shape of structures, formed during its development. The effect of heat flux density on the time of boiling-up expectation and structures of evaporation fronts is shown for different Reynolds numbers. According to new experimental data on decay dynamics of falling wavy films with transient heat generation for subcooled water, the crisis phenomena development is significantly effected by the condensation effect at boiling incipience.
