- Abstract
- This report presents the results of a systematic investigation of the effect of wind on liquid pool fires. The primary result of the investigation was the measurement and correlation of flame angles of tilt. In addition, data were obtained for fuel burning rates, flame size, flame radiation, and wake gas temperatures. The unexpected phenomenon of flame trailing was measured and correlated. Analysis of the flame bending data was facilitated by assuming a model of the wind-blown flame and using a momentum balance equation to express the flame bending mathematically. Dimensional analysis was used to determine the relevant parameters for the data correlations. The extent of flame bending was found to depend primarily on the Reynolds number, the Froude number, and the ratio of fuel vapor density to ambient air density.
