- Abstract
- JASMINE, a field model based on the computationalfluid dynamcis program PHEONICS, was used to model the National Institute of Standards and Technology (NIST) fire tests conducted within an aircraft hangar in Texas. The purpose of this study was to determine the capability of JASMINE when applied to high bay type spaces. The facility test area measured approximately 389 meters wide, 81 meters deep, and 30.4 meters high. Draft curtains extending 3.7 meters down from the ceiling, spaced at 1'2.5 meters, were installed perpendicular to the front sliding doors and extended from the sliding doors to the rear fire wall. The fire source for the test consisted of an array of nine, 0.91 meter by 0.91 meter pans, 0.076 meters deep, arranged to form a 7.5 m² square with 15 gallons of technical grade isopropyl alcohol. The fire was centered under one draft curtain area. NIST estimated the fire heat release rate from previous experiments to be 8,250 kW. Steady state and transient simulations were performed. The transient simulation reached a steady state condition after 180 seconds of simulation time. Results from steady state and transient simulations agreed within several tenths of degrees Celsius. The JASMINE predicted and NIST measured temperatures were compred at various points below the hanger ceiling for both simulations. Overall, the JASMINE simulation was shown to predict the thermocouple measurements reasonably well.
