Résumé:
This work is a contribution to the numerical study of gas turbine cycles, more specifically; it studies the final state of combustion. The numerical analysis is based on a ten-dissociation sub-reactions kinetic model of Ethylene, which allows the calculation of the reaction products molar fractions using a Newton-Raphson method based Matlab code, which at first requires the calculation of the Jacobian matrix for the 11 variables system. The mole numbers will be
then injected into a Bisection method based Matlab code, which uses the both, the reactants and products enthalpy to guess the adiabatic flame temperature up to a maximum precision.
The study also includes an Ansys simulation of a combustor model made in SolidWorks with the measures of the P9005 micro-gas turbine combustor, which allows for a comparison between the Matlab Program Results, the simulation results and some results and benchmarks runs from different articles. The study also includes the effect of pre-heat inlet air on the final temperature and the parameters contributing to the production of pollutant in the products.
