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

RESUMO

This work numerically studies the heat transfer and fluid flow of an inclined solar still cavity. These devices convert saline or low-quality water into potable transporting water vapor from a warmer surface to a cooler one. The phenomenon of double-diffusion natural convection is considered. The solar still cavity has top and bottom sides inclined and subjected to temperature and concentration gradients, while the vertical walls are adiabatic. Water vapor is considered to be at the saturated state. The governing equations are conservation of mass, energy, momentum, and concentration. The conservation equations are coupled, and their solutions are based on the semi-implicit method for pressure-linked equations (SIMPLE) algorithm. Velocity, temperature, and concentration fields are obtained for a Rayleigh number range in which laminar flow prevails, and for different cavity inclination angles and aspect ratios. The results show that for high Rayleigh numbers an increase in cavity inclination causes the Nusselt and Sherwood numbers and the solar still condensation rate to increase. When the aspect ratio is decreased, the Nusselt and Sherwood numbers also decrease; however, the condensation rate increases due to the increment of the condensable area. A solar still cavity of good thermal performance presented an inclination angle of 45° and an aspect ratio of 1/12 when the thermal Rayleigh number was 106.
