Sažetak
This research presents the numerical modelling of the jet engine can type combustion chamber. The modelled chamber is equipped with a double stage radial swirler used for achieving a more uniform stream of hot gasses. The constant mass flow of air and n-decane liquid fuel is entrained in the combustion chamber. To model the turbulent behaviour, the advanced k-zeta-f turbulence model was utilised, while the spray process was described using the Euler Lagrangian discrete particle approach. The combustion process was described with the general gas phase reaction approach and by using tabulated kinetics, while the ignition was modelled by using the spark ignition model. The differences between two applied combustion approaches were analysed, and the conclusions have been shown. In both approaches, the JP10 SanDiego chemistry mechanism was employed where thermodynamic properties of JP10 species were modified for temperature range above 1000 K. Presented results, such as temperature and velocity distribution are in good agreement, and an excellent chemical and physical behaviour of chosen setup were achieved. All simulations were performed with the computational fluid dynamic software AVL FIRE™, while the chemistry tabulation was done with AVL TABKIN™.
