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: 0.5 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: 0.8 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: 0.2 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: 0.00018 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: 0.11 SJR: 0.286 SNIP: 1.032 CiteScore™:: 1.6 H-Index: 10

RESUMO

This paper presents a theoretical modeling and numerical and experimental investigations of the laminar convective condensation inside a circular smooth tube. The developed model includes the interaction between the surface tension, gravity, and shear stresses at the vapor-liquid interface and its cross influence on heat transfer. The influence of the gravity force, tube diameter, and temperature drop on the heat transfer at in-tube condensation of pure ethanol vapor is considered. The heat transfer coefficient as a function of the inclination angle of the condenser tube and the temperature drop between the vapor saturation and the wall temperatures is measured. A comparison of the experimental and numerical data is performed. The results of the numerical calculation are in good agreement with the experimental results. Numerical experiments have been carried out with the aim of predicting the time length of the transition to the steady-state regime after an abrupt change of the gravity level. It is shown that the transition time to the steady-state regime increases with an increase in the diameter of the condenser tube. The transition time to the steady-state regime under microgravity conditions is longer than that under normal gravity for a tube with a diameter larger than the value close to the capillary length of the working liquid.
