Modified Quasi-Steady Fuel Droplet Combustion Model

Abstract EN

The quasi-steady model of the combustion of a fuel droplet has been modified.

The approach involved the modification of the quasi-steady model to reflect the difference in constant properties across the flame front.

New methods for accurately estimating gas constants and for estimating Lewis number are presented.

The proposed theoretical model provides results that correlate favorably with published experimental results.

The proposed theoretical model also eliminates the need for unguided adjustment of thermal constants or the complex analysis of the variation of thermal properties with temperature and can serve as a basis for analysis of other combustion conditions like droplets cloud and convective and high-pressure conditions.
