- Description
- A combined experimental and modelling study was carried out to investigate the flame spread phenomenon over a porous bed wetted with finite quantity of super-flash liquid fuel. Measurements included flame spread rate, temperature distribution, and visual observation. Sand particles ranging from 0.5 to 5 mm and Propanol (flash point 12 °C) were used as porous bed and liquid fuel, respectively. Results corresponding to the rate of flame spread show that regardless of airflow speed and/or direction the rate of flame spread decreases as either the bed depth or particle size increases, however the flame spread deceleration rate is more distinct under opposed airflow. Temperature measurements and mathematical modelling results indicated the existences of three different temperature regions in the bed. The magnitude of temperature in upper region was significantly larger than those of the lower region. The modelling results were in good agreement with the experimental data.
