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

要約

A numerical simulation has been carried out which predicts the growth and wall heat-transfer characteristics of a bubble atop a heated flat surface in an otherwise quiescent pool of liquid. In accordance with the experimental conditions and observations of Merte et al. (1995), the simulations are carried out on a constant heat flux surface in microgravity, and the bubble maintains a hemispherical shape with no contribution of a microlayer. The model, computational technique, and interface tracking methodology provide very high spatial and temporal resolution. This is true for the micrometer-sized nucleus in metastable equilibrium with its surrounding liquid at the end of the measured waiting time, through the surface tension, transition, and heat transfer controlled growth domains where the bubble expands to macro-sized. The simulations indicate that the rapid depressurization of the vapor bubble as it expands occurs in conjunction with a like drop in the vapor temperature. This establishes a substantial temperature gradient and subsequent evaporative cooling effect of the heater surface near the moving triple interface. The influence of bulk liquid advection and transient conduction is discussed in relation to the bubble dynamics.
