Effects of the change of the cross-sectional area of the can-annular combustion chamber on the combustion
flow
NO_x formation and NO_x emission in the combustion chamber are studied by numerical simulation.The results show that
the main recirculation zone is formed at the outlet of the main nozzle of the can-annular combustion chamber
the outer recirculation zone is formed in the boss area
and the range of outer recirculation zone is small.As the cross-sectional area increases
the range of the main recirculation zone increases and the temperature peak and high-temperature zones decrease.Increasing the cross-sectional area reduces the specific area heat intensity
the temperature level of the combustion chamber
the thermal NO_x formation rate and the NO_xemissions from the combustion chamber.
