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

Thin liquid films flowing down vertical or inclined plates are widely used in many industrial apparatuses. Using structured plate surfaces often leads to heat transfer enhancement. In the present work, a numerical model for heat transfer in a thin liquid film flowing down a heated, inclined, and grooved plate is developed. To this end, the Graetz-Nusselt problem for falling films on structured plates is solved. The computed velocity field and the developed temperature field, as well as the temperature distribution in the thermal entrance region of a falling film, are presented. The dependence of the temperature distribution on the Reynolds number, Biot number, applied heat flux, plate inclination angle, and plate topography is investigated. It is shown that the film rupture on the groove crests, which is observed in experiments at relatively high heat fluxes, can be attributed to the strong interface temperature gradients developing in the thermal entrance region. To qualitatively validate the numerical model, the hydrodynamics and heat transfer in falling films on structured plates are studied experimentally and simulated using the CFD tool FLUENT. The numerical results of the Graetz-Nusselt problem are discussed and compared with the experimental values and results of the FLUENT simulations.
