Ignition and Propagation Rates for Flames in a Fuel Mist.

摘要

A mathematical model was developed, which is capable of predicting the burning velocity in polydisperse air-fuel sprays given the initial conditions of the liquid and gas phases. The analytical predictions were tested against previous experimental data, and the agreement was satisfactory. The burning velocity in polydisperse kerosene-air sprays was measured at constant air-fuel ratio, and for various degrees of atomization of the spray in order to further check the predictions of the mathematical model. The results were also in good agreement with the analytical predictions. (Author)
