Abstract

The knowledge of the fire safety distance of the multiple pool fires is essential to model, manage, and mitigate the fire hazardous scenarios to safeguard the surrounding people, buildings and equipment. In this work, experiments are performed on 0.1 m gasoline double pool fires to calculate the fire safety distances using an infrared imaging technique. The distance (S/D) between the two pool is varied from 0 to 1. The irradiance from the two pools is calculated using the two-dimensional temperature field obtained by an IR camera. The calculated irradiance along the flame axial direction and on the ground is presented in a contour format. The safety distances are also represented as a function of their respective flame lengths. Two threshold heat fluxes: (I) 1.4 kW/m2 and (II) 4.7 kW/m2 which are required for human safety are emphasised in the contour plots for all the configurations.
