Abstract
Pulsating and uniform spread across n-propanot and ethanol liquid fuel pools is simulated via a two-dimensional, transient, numerical model which incorporates finite-rate chemical kinetics, variable properties, and a partially adaptive finite-difference gridding scheme. The model is compared to detailed, independent experimental data. The explanation and characterization of the pulsating and uniform flame spread phenomena are developed Pulsating flame spread requires a gas-phase recirculation cell just forward of the flame. δ flow This cell entrains evaporating fuel vapor. The size and existence of the recirculation cell is determined by the extent of liquid motion ahead of the flame (δ flow) and by opposed flow in the gas phase, naturally induced by buoyancy. The amplitude and period of the pulsations each increase with δ flow Over the range of pool depths that were investigated (2 to 10 mm) the liquid-phase flow is primarily affected by large surface-tension variations along the liquid surface and not b...
