- Abstract
- The first report in this study discussed the design and construction of a low-speed wind tunnel and static test facility for the investigation of free-burning, liquid-fueled fires. The second report presented the results of experiments on the effects of wind on flames from burning liquid pools. Data on the interaction effects of small liquid pool fires were also presented in the second report. The wind tunnel tests described in the second report were designed primarily to measure the angle to which the flame was tilted from vertical because of the effect of the wind. Only low wind velocitis were required for the measurements of flame tilt. However, it was found during those low-speed tests (up to about 5 ft/sec) that the wind caused two other important effects on liquid-fueled fires: the burning rate decreased as the wind velocity increased and the flame trailed downwind of the burner due to the wind effects. Extended measurement son the effect of wind on liquid fuel burning rate and the flame trailing phenomenon were both investigated over a wider range of wind velocities and are discussed in this report.
