Correlating performance parameters for fuels, such as ring carbon, aromatic percentage, carbon number, C/H mass ratio and hydrogen percentage, have proved to have relative correlating deficiencies. Although hydrogen percentage is the most successful, so far, it is postulated that the Gibbs function is more powerful owing to its direct relation with the chemical potential, which causes reactions to take place. This parameter gave favourable trends when checked against different previous works on gas turbine combustors especially with flame radiation, smoke and liner temperature. However, improvement over hydrogen content is marginal.
