Abstract
Ordinary droplet and spray combustion arise, for instance, by injection of a liquid fuel into a hot environment. After injection the liquid fuel eventually breaks up into small droplets that evaporate, ignite and burn. The Diesel engine provides a practical example of such a process. The interaction of droplets and sprays with a gaseous phase are particularly complex, if the gaseous phase is a flame that is self-sustained by gaseous fuel and oxidizer. Such flames are termed “two-phase flames”, and they are the objective of the present study. Suppression of explosion or extinction of fire by water sprays provides practical examples of the occurrence of two-phase flames. The two-phase flames modelled and simulated in the present work are counterflow flames, i. e., flames in a flow field generated by directing two gaseous streams towards each other. One of the gaseous streams carries a combustible fuel-air mixture and the water droplets, the other stream carries a flow of hot combustion products.
