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: 1.2 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: 1.8 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: 0.00095 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: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

Краткое описание

This paper presents a computational study of the effect of water-spray characteristics on the suppression of a large-scale (2 m × 2 m) JP-8 pool fire in a 10 m × 10 m × 10 m compartment with an open ceiling. The numerical model is based on an unsteady Reynolds-averaged Navier−Stokes formulation using a stochastic separated flow approach for the droplets that includes detailed descriptions of the interaction between water droplets and fire plume. Simulation results indicate that water-spray injection causes the gas temperature to rise due to the initial enhancement of the turbulent mixing. A threshold suppression condition is achieved when the injected droplet carries enough momentum (injection speed range is 20−80 m/s) to penetrate the fire plume and evaporate in the flame regions where most of the gas-phase combustion is taking place. In addition, the droplet size (ranging from 100−800 μm) should be small enough to yield quick evaporation when in contact with the flame surface for efficient cooling. Based on a parametric study, a preferred fire suppression configuration is recommended for the systems considered.
