Chemical kinetic analysis of an alternative fuel for aircraft

Abstract

One of the main aspects of design aircraft engines is to verify the effect on the environment in order to abide by the increasingly strict rules for pollutant emissions.

The purpose of this thesis work is the study and analysis of a new fuel derived from renewable sources. In particular using numerical methods, the behavior of chemical kinetics is carried out in transient conditions, one representative of a surrogate of Fischer-Tropsch (F-T), composed of n-dodecane, n-decane and iso-octane, and one representative of a traditional fuel currently in use on the aircraft traffic, consisting of n-d ecane, iso-octane and toulene.

The curves of ignition and extinction are studied at different equivalence ratio and residence time for both the kinetics and then the results are compared in order to obtain guidance on the possibilities and limits of use of bio-fuels in aeronautical propulsion.
