Abstract
An axi-symmetrical two-dimensional mechanistic model of gas turbine combustors has been developed which enables us to make point-by-point arguments on the formation and destruction of nitric oxide taking both chemical reactions of finite rate and turbulent transport processes into account simultaneously. Two-dimensional distribution maps of velocities, temperature, nitric oxide concentration and equivalence ratio, as well as the variation of combustion efficiency in axial direction have been obtained numerically for a small combustor of can-type and the effects of combustor parameters on nitric oxide emission have also been discussed.
