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

ABSTRACT

This work investigates the influence of alternating current electric fields on the flow patterns, associated heat transfer, and power penalty during convective boiling of HFE7000. A single-pass counter-flow heat exchanger is employed, whereby heated water flowing in the shell side transfers heat to the two-phase HFE7000 fluid flowing within the tube side. In a novel design feature, optical transparency is achieved by using a sapphire central tube surrounded by a Perspex water jacket containing the heated water. A stainless steel rod running concentrically through the tube acts as an electrode while the outer surface of the sapphire tube is coated with a thin layer of indium tin oxide forming an electrically conductive and optically transparent ground to establish an electric field across the working fluid. This unique test setup facilitates visualization of the flow patterns caused by the electrohydrodynamic (EHD) forces and allows high-speed videography of the HFE7000 while boiling. Tests were performed at a low mass flux (100 kg/m2s) and fixed average heat flux (12 kW/m2)for inlet qualities of 2%, 15%, 30%, and 45% and applied voltages of V = 0, 4, and 8 kV. The results show that the average heat transfer coefficient improves with applied voltage over the entire range of qualities tested. However, as inlet quality increases the heat transfer enhancement tends to decrease, as does the electrical power required for EHD (EHD penalty). Conversely, pumping losses were seen to increase as inlet quality increases.
