Sažetak
In this research, numerical modelling of kerosene fuel inside a can type combustion chamber of a jet engine is presented. The observed chamber is designed with a double stage radial swirler used to induce the air vortices. The constant mass flow air is defined at the combustion chamber inlet in order to supply the combustion zone with fresh oxygen. The liquid fuel entitled Jet-A was used as a surrogate for the kerosene fuel. To model the turbulent behaviour, the advanced four equation k-zeta-f turbulence model was utilised, whilst the transient spray process was described by the means of the Euler Lagrangian approach. The combustion process was described with the validated ECFM-3Z combustion model, and the ignition was modelled with the Issim spark ignition model. The influence of spray process was analysed by varying the spray angle and number of nozzle holes. Presented results, such as temperature fields, velocity profiles and emission concentrations through the entire combustion chamber were verified. According to the provided results, a correct chemical and physical behaviour of chosen setup were achieved. All simulations were performed with the commercial computational fluid dynamic software AVL FIRE™.
