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

Abstract

Gas mixing rates were studied in a 5000-liter cylindrical tank by observation of gas temperatures with thermocouple probes during pressurization from 1 to 2 atmospheres through a nozzle 25.4 mm in diameter in ca.14 seconds. Pressurants 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.
