NRL 324-cu m Chamber Pressurization Experiment: Pressurant Concentration Histories with and without Obstacles to Flow.

Abstract

Nitrogen pressurization of pressurizable enclosures is proposed for fire suppression. Implementation requires pressurant distribution information. Distribution histories, with and without flow obstacles are reported as inferred from temperature measurements observed during pressurization of a 324 cu. m fire chamber from 1 to 2 atmospheres (101.3 to 202.6 kPa). For pressurant injection times of 10 and 30 s, pressurant and resident gases were judged to be well mixed within 1.6 injection times, and no grossly unmixed pockets were observed. (Author)
