Abstract:
Electrical models based on partial scaling principles neglecting molecular transport parameters have been built to scale the gross flow features of a mass fire down to laboratory size. Data in the report were obtained with two models which, when placed in a corner, simulated quadrants of a 2 foot by 2 foot and of a 4 foot by 4 foot fire. Both models consist of square arrays of electrical heating elements. Inflow air velocities at the edge of the models and updraft velocities in the hot air column above the models are measured with a hot wire anemometer. Air temperatures in the column are measured with chromel-alumel thermocouples. The heat release rates used in the models corresponded to the scaled down estimated rates at 5 and 18 minutes after ignition in the June 1966 Project Flambeau fire. Author
