Title: The new and improved NIST Dragon‰s LAIR (Lofting and Ignition Research) Facility: Coupling the Reduced Scale Continuous Feed Firebrand Generator to Bench Scale Wind Tunnel
Published: October 12, 2011
Abstract: The present investigation was undertaken to construct a new and improved Dragon‰s LAIR facility. This entailed removing the NIST Baby Dragon from the wind tunnel facility and inserting the new and improved NIST continuous feed Baby Dragon. The unique features of the continuous feed Baby Dragon, as opposed to the present NIST Baby Dragon, is the capability to produce a constant firebrand shower in order to expose building materials to continual firebrand bombardment. The efficacy of the new experimental facility to determine ignition regime maps of building materials exposed to wind driven firebrand showers is presented. Specifically, ignition regime maps are presented for cedar crevices as function of firebrand generation rate with fixed wind tunnel speed, and variable cedar moisture content.
