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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

Краткое описание

This paper utilizes computational fluid dynamics (CFD) to investigate the ventilation system within the cabin of an armored vehicle. Commercial ICEM/CFD software is employed to construct a model of the armored vehicle and FLUENT simulation software is applied to a turbulence model to perform steady- and unsteady-state analysis of the ventilation system under various imposed housing temperature conditions. The simulation results provide a complete analysis of the temperature distributions, velocity vectors, PMV indices, and local mean age of air in the cabin under steady-state conditions. In the unsteady state, the air emission speed increases with increasing temperature when the housing is assumed to be isothermal. Therefore, incorporating a heater within the housing is likely to enhance the discharging of unclean gases. In the case of a heat insulating housing, the air emission speed is bounded by the emission speeds of the isothermal 10° C and 30° C housing temperature cases. Therefore, there is no clear correlation between the insulated and isothermal cases. The present unsteady-state analysis results are also applicable to general heat insulating films. Hence, the present results provide a valuable contribution to the development of enhanced ventilation systems for general industrial or military applications.
