NRL 5-m3 Chamber Pressurization Experiment: Pressurant Concentration Histories.

Abstract

Gas-mixing rates are inferred at interior locations of a minimally cluttered 5-cubic meters chamber from temperature measurements during pressurization from 1 to 2 atmospheres (101.3 to 202.6 kPa) with an inert pressurant gas, a proposed method of fire suppression. Analysis for this inference is presented and experimental data are reduced accordingly. In addition, the data support a scale modeling theory already reported. These findings show that, for injection times of 10 to 30 seconds, good mixing is experienced in 1.5 injection times in this minimally cluttered space. (Author)
