Wind and slope effects on laboratory-scale fire behavior

Wind and slope interaction effects on rate of spread, flame length and flame angle were examined in 65 fires in an open-topped tilting wind tunnel. Fuel beds consisted of vertically-oriented birch sticks and horizontally oriented aspen excelsior. A complete factorial experiment with five wind velocities (-1.1 to 1.1 meters/second) and five slope angles (-30 to 30%) arranged in a randomized complete block design was replicated twice. Flame rate of spread, flame height, and flame angle were measured using thermocouples and video imagery. Moisture content of 60 fires was 11%; 5 fires had a fuel moisture content of 35%. This data publication includes data summarizing the 65 fires, velocity profiles measured in the wind tunnel, and raw thermocouple data for the 65 fires.
