Method and system for evaluation of fire suppression systems performance

ActiveUS9355062B2Compact formatUnprecedented accuracy and ease of useDigital computer detailsNuclear monitoringData compressionKinematics
An initial (near-field) spray generated by a sprinkler under study is fully characterized using a laser-supported Shadowgraphy / PTV system. Near-field spray characteristics are established from local measurements, which are mapped in a spherical coordinate system consistent with the kinematics of the spray. A novel data compression scheme is introduced to generate analytical functions describing the sprinkler spray based on the measurements. These analytical functions are useful for initiating the sprinkler spray in computational fluid dynamics (CFD) based spray dispersion and fire suppression modeling. The near-field spray measurements and associated data compression approach are validated by comparing volume density measurements 1 meter below the sprinkler with volume density predictions generated from spray dispersion calculations initiated with the analytical spray functions.
