    Abstract
  • The combustion characteristics of the self-stabilized dual-swirler cup in the unconfined case,which is suitable for the tangential trapped vortex combustor,were investigated experimentally.The self-stabilized dual-swirler cup is characterized in that,the dual-swirler with radial holes is employed,and the fuel sprays from a pressure nozzle in the center.According to the different swirl numbers and air flux distributions of the swirler,different layouts are developed.In the experiment under normal temperature and pressure,RP-3,for example,was used as the fuel.Results show that,the flame stability increases and the length and shape of the flame remain unchanged with the decrease of the air flux distribution of the internal swirl and increase of its swirl number.
