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

ABSTRAKT

Natural convection and radiation in a non-gray participating gas mixture in a differentially heated square enclosure is studied numerically. The commercial package ANSYS Fluent 14.5 is used to solve the equations governing flow and energy by the finite volume method. The volumetric radiation source term in the energy equation is governed by the radiative transfer equation (RTE) and it is solved using the discrete ordinates method (DOM). The non-gray behavior of the gas mixture is modeled by the spectral line weighted sum of gray gases (SLW) approach. For an emitting and absorbing medium, the spectral absorption coefficient is modeled alternatively as a gray-SLW temperature dependent quantity, evaluated using the SLW model. User defined functions have been developed to incorporate the radiation source term in the heat transfer equation, while solving the governing equations using Fluent software. The effect of gas mixture mole fraction variation (CO2, H2O, and N2), wall emissivity, Rayleigh number, and convection-radiation interaction are studied. The presence of non-gray gas radiation substantially changes the temperature and flow patterns in the cavity. The results show an augmentation in total Nusselt number and reduction in convective Nusselt number. Comprehensive correlations for total Nusselt number by convection and radiation heat transfer modes are developed which provide insight into the physics associated with the problem.
