Abstract
Analytical models existing in the open literature for gas turbine continuous flow combustors are reviewed and discussed from the point of view of predictions of pollutant emissions. Particular emphasis is placed on the kinetic aspects of the models involving liquid fuel droplet evaporation and/or combustion and homogeneous chemical kinetics for hydrocarbon/air combustion. A brief summary of the various flow models is also included. Comparisons with data obtained from experimental or practical combustors are made where appropriate, and suggestions for further research are listed.
