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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

摘要

The study presented in this article aims at mapping experimentally the flow patterns in the annulus between an internally heated inner cylinder and a surrounding outer cylinder with an aspect ratio of length/diameter ~1. Both cylinders are stationary. The annulus is open axially to the ambient at both ends, and natural convection ensues when the inner cylinder is heated. The experiments are performed at temperatures of 32.2 °C (90 °F) and 65.6 °C (150 °F), corresponding to Rayleigh numbers (RaL = gβL3(Ti - T /να) of 6.62 × 103 and 1.58 × 104 , respectively. This range encompasses the region in which stable laminar flow transitions to unstable laminar flow of higher intensity. The full flow field tracking (FFFT) method utilized in this study uses a coherent laser light sheet to illuminate sequential sections of the annulus, while a low-luminosity camera equipped with a long-distance microscope is coupled to a video recorder for recording the flow patterns.
