Combustion Scaling and Modeling: Fire Suppression By Nitrogen Pressurization: IV - Test Data, NRL-5000 Liter Facility, Test Configurations 1, 2, and 3

Abstract

Gas mixing rate studies in a 5000-liter cylindrical tank continue. Observations of gas temperatures are made with thermocouple probes during pressurization from 1 to 2 atmospheres through one, two, and three-nozzle arrays with diameters of 15.2 mm in ca. 30, 15, and 10 s, respectively. Pressurant concentrations may be inferred from temperature measurements. Nine experimental runs are reported in which air is used as both the pressurant and the resident gas under nonfire conditions with no flow obstacles.
