- Abstract
Pool spacing and cross wind are responsible for the fire spread from one pool to the others. However, the influences of cross wind on the characteristics of flame interaction between two adjacent liquid fires have little been studied yet. In this work, a series of n-heptane pool fire experiments were conducted. The results showed that, apart from the radiation effect, the upstream flame has a shielding effect on the downstream flame. This restricts the downstream flame air entrainment and causes a negative effect on fuel burning. The flame tilt angle is determined by the combined effects of horizontal wind and vertical fire buoyancy, and is also related to the pool spacing. A dimensionless correlation is proposed to illustrate the effect of pool spacing on the tilt angle. When the two pools are attached, the burning rate is relatively low due to the mutual restrictions of air entrainment, compared to the cases with some pool spacing. Both cross wind and pool spacing indirectly affect the flame length by changing the burning rate. An optimized correlation well predicts the flame length when continuous flame merging does not happen. The flame merging probability increases with decreasing pool spacing and increasing wind velocity.
