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: 2.3 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: 1.8 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: 0.00037 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: 0.6 SJR: 0.433 SNIP: 0.593 CiteScore™:: 4.3 H-Index: 35

SINOPSIS

This study investigates the effect of evaporator confinement on the performance of an enhanced microstructure based thermosyphon, that has shown very high heat transfer rates (upto 100 W/cm2). The enhanced structure used demonstrates almost 2.5 times increase in the heat transfer compared to a solid block of the same size. The top spacing between the microstructure and the cover of the evaporator was varied and its effect on heat transfer was studied. The results for the effect of sidewall spacing show that the influence of confinement on the boiling performance of the microstructure is negligible. Total blockage does deteriorate the performance at very high heat fluxes (40−70 W/cm2). However, a minute gap of the order 1.5−3 mm is sufficient to get to performance levels close to boiling in a large enclosure. The response of the confined setup was then studied under suddenly applied loads. This is of particular importance to practical applications where a sudden temperature excursion could be detrimental to electronics. The results show a very smooth transition from startup to steady state. No incipience excursion was observed in any of the runs.
