摘要： A method is disclosed for evaluating inerting concentration of a fire suppression agent. The method includes flowing air upward into a chimney tube and flowing fuel into the flowing air in the chimney tube. A targeted concentration of the fire suppression agent is introduced into the flowing air and into the flowing fuel in the chimney tube. An ignitor is ignited to provide ignition energy to the flowing air and the flowing fuel, and the ignitor is deactivated. The targeted concentration of the fire suppression agent is at or above the inerting concentration of the fire suppression agent if combustion of the flowing fuel does not persist beyond three seconds after the ignitor is deactivated.

摘要： A fire suppressant system, including: a nozzle having a passage wall that defines a converging-diverging passage, having: an inlet, an outlet downstream of the inlet, and a throat region that includes a converging portion and a diverging portion; a cone within the passage, having an upstream apex located within the diverging portion and a downstream end located within the passage and adjacent to the outlet, the cone has a radial outer wall that defines an exhaust passage with the passage wall, and the cone has a plurality of axial segments with differing segment cone angles, including: a first segment at the upstream apex of the cone that has a first cone angle such that the exhaust passage narrows along the first segment; and a second segment that is adjacent to the first segment and that has a second cone angle such that the exhaust passage expands along the second segment.
