In this paper, the effect of airflow speed on flame length of liquid pool fires has been experimentally studied based on a small-scale wind tunnel, where the airflow speed was varied from 0 to 2.93 m/s during the tests. Different sizes of the pool with 2, 3, 4, 6, 8, and 10 cm diameter were considered. The experimental results show that with increase of , the non-dimensional flame length of alcohol pool fire firstly increases and then decreases after exceeds 8.0, while the non-dimensional flame length of n-heptane pool fire increases with increase of. It was also found that the flame length response to the airflow speed correlates to heat release rate of the fire, which was seriously influenced by combustion efficiency. A model was also developed for predicting flame length of a pool fire influenced by airflow with. [ABSTRACT FROM AUTHOR]
