It is of great importance to understand the combusting flow fields in combustors for efficient design and improvement of low-NOx aircraft engines. In this study, a sub-scale combustor with a realistic air-blast atomizer is newly fabricated, and the internal combusting flow field is measured using a PDA (Phase Doppler Anemometry). It is observed that blue flame indicating premixed-like flame with low equivalence ratio appears in the upstream region, whereas luminous flame indicating diffusion-like flame with high equivalence ratio appears in the downstream region. Up to half the fuel droplets are circulated in the recirculation zone and the droplets' motions are strongly affected by flow rates of air and fuel. The observation and qualitative data obtained in this study would be very useful for the validation of the numerical simulations of spray combustion.
