A Numerical Analysis of the Flow Characteristics in a Lean Premixed Gas Turbine Combustor for Power Generation

발전용 희박예혼합 가스터빈 연소기 내부유동 특성 해석

Three dimensional CFD investigations are carried out to understand the complex flow field in a gas turbine combustor with multi-element fuel injectors. The gas turbine considered here is the GE7FA model which has aye fuel injectors in each combustor can and utilizes lean-premixed combustion to meet nitric oxide emission requirements. Detailed three-dimensional flow characteristics and fuel-air mixture formation process inside the fuel nozzle and gas turbine combustor including five swirl nozzle tips are analyzed using commercial FLUENT code.
