Theoretical and numerical analysis of fuel droplet combustion process with conventional and transient models

Abstract EN

The study introduces a theoretical analysis and numerical solution for the combustion of a hydrocarbon fuel droplet inside the combustion chamber.

The study employs two mathematical models to analyze the combustion process.

Conventional (Classical) model and Transient model.

The combustion process of a stagnant droplet in the steady state was analyzed in the classical model, while, In the transient model, it was assumed that there is a period of time in the stages of the droplet combustion in which the droplet is heated before combustion.

The effect of change in temperature on the thermo-physical properties of the fuel was adopted through the two models.

For the classical model, a convenient approximation was adopted for the heat transferred inside the droplet.
