Abstract
The burning of a liquid fuel from a pool in the laminar regime is investigated theoretically by using a rigorous model of the phenomenon. The relevant conservation equations were solved numerically to yield the velocity field inside and around the flame, the temperature profile, the spatial distribution of the reactants and the products of combustion, and the evaporation profile along the pool radius. Based on those fields, the average liquid regression rate and the flame height were correlated with some dimensionless groups. A quantitative comparison with other models was carried out and some disagreements were discovered and discussed. It is concluded that the buoyancy forces play a significant role in determining the structure of the velocity field inside the flame, as well as the mechanism by which heat is transferred to the liquid surface. Furthermore, the flame characteristics were found to be significantly dependent on the evaporation profile along the radius, and hence on the buoyancy forces.
