Based on a testing platform of a small-sized reverse combustor
the effect of different axial locations of fuel nozzle in the swirler on combustor outlet temperature field is studied by experiment.And
the experimental results are also compared and analyzed.Experimental data show that
for the same combustor
there is an optimized axial location between the fuel nozzle and the swirler.In such case
the pattern factor of outlet temperature is minimum;Under the operating state of the same combustor
the optimized axial location of the fuel nozzle changes with the fuel nozzle spray angle.This study thus provides an effective technical approach to adjust the outlet temperature field and develop the combustor.
