The effects of wind pressure on mass burning rates of alcohol pool fires in an inclined wind tunnel

Abstract

In order to study the effects of different wind direction on combustion characteristics of alcohol pool fires, an inclinable wind tunnel was developed for providing venting wind with different directions. The control parameters of the experiments include the tunnel wind velocity, which can be altered from 0 to 3.0 ms –1 , and the tunnel inclination angle, which can be sloped from 0°to 30°while the fuel pan keeping horizontal inside the tunnel. The results show that the mass burning rate increases faster with increasing the slope angle of the wind tunnel when the wind speed is less than 1.5 ms –1 .I n addition, a relationship between the mass burning rate of the pool fire and the wind direction has been determined, that agrees well with the experimental results.
