RÉSUMÉ

In the present article, the influence of variation of percentage of distributed air flow rate by a swirler, as well as primary and dilution jets on reactive flow characteristics in a model, wall jet can combustor is investigated. The realizable k-ε turbulence model, discrete ordinates radiation model and laminar flamelet combustion model are employed to simulate a reactive two-phase flow. Four different cases of air injection are studied. Results show that an increase in air percentage of primary jets makes a stronger recirculated flow to take place toward the center of a combustion chamber, before primary jets. Also, a maximum difference in the temperature profiles for all four cases of air distribution occurs near the injector. In addition, air distribution of case 1 based on laboratory conditions, is not optimal and there are minimum CO2 and maximum C concentrations. In case 3, where the highest percentage of air flow belongs to primary jets, less NO emission is produced and distribution of the outlet temperature is more uniform. Furthermore, combustion process is more complete as compared with cases 1 and 4.
