Abstract
This paper deals with the study of the pressure effects on the burning in air of large hydrocarbon fuel droplets. The traditional quasi-steady analysis fails to predict any pressure dependence of the burning rate, except a very minimal amount due to nonuniform gas properties. Experimental results of this study and others, in the range from 1-20 atm, indicate that the burning rate of liquid droplets is however dependent on the ambient pressure. An equation has been developed incorporating our observations which predict a pressure effect when the variation of the flame standoff distance with pressure is given. The pressure effect on the burning rate constant, K, appears to be small. The power law relationship is found to be proportional to p.14 for ethanol and p.11 for n-propanol.
