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: 1.7 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: 1.4 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: 0.00072 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: 0.43 SJR: 0.318 SNIP: 0.568 CiteScore™:: 3.5 H-Index: 28

RÉSUMÉ

An internally cooled hexagonal parallel-plate membrane contactor is developed and used to study the conjugate heat and mass transfer under the effects of cooling tubes. The contactor is comprised of a series of internally cooled hexagonal parallel-plate membrane channels (IHPMC). A mathematical model is established in a unit cell including a hexagonal plate membrane, an adjacent air channel and a solution (liquid desiccant) channel with several cooling tubes. The air and the solution streams are in an arrangement combined with counterflow and crossflow. The cooling tubes are installed in the solution side, while the water flows in the counterflow arrangement to take away the sensible heat of the solution generated by absorbing the water vapor. The partial differential equations for describing the fluid flow and heat and mass transfer are established and numerically solved. The friction factors, Nusselt numbers, and Sherwood numbers are then obtained and analyzed. Influences of the tube number Ntube, tube outer diameters douter, and Reynolds numbers Re on the IHPMC under the conjugate heat and mass transfer boundary conditions are investigated. It can be found that the tube numbers and the tube outer diameters have negligible influences on the mean Nusselt numbers and the Sherwood numbers for the air stream, while their effects on the solution are large. The friction factors and the Nusselt numbers for the water stream are nearly independent of the various tubes inside the solution channels.
