Abstract In order to comprehensively evaluate the flow and heat transfer performance
of a large-size annular combustion chamber of a heavy-duty gas turbine, we carried out
numerical computation and analyses on the velocity, temperature and pressure fields in
the chamber with double swirlers. The mathematical model of the coupling combustion,
gas flow, and heat transfer process was established. The influences of the inlet swirling
strength, fuel-air ratio and temperature of the premixed gas on the multi-field
characteristics and synergy were investigated on the basis of field synergy theory. The
results showed that the central recirculation zone… More >
