ABSTRACT
Combustion of liquid fuels differs from the combustion of gaseous fuels in that a liquid fuel must be vaporized and then combusted. This additional step adds a signi–cant complication to the combustion process. In the analysis of gaseous fuel combustion systems, we were concerned about the energy density of the fuel, the reaction rate, the heat release rate, the ¢ame temperature, and the ¢ame speed-all of which are coupled together. In the analysis of liquid fuel combustion systems, we are again concerned about the energy density of the fuel, the reaction rate, the heat release rate, the ¢ame temperature, and the ¢ame speed; but the rate controlling phenomenon is the evaporation of the fuel.
