摘　　要：一、前言 在涡轮风扇发动机加力室外函和冲压发动机燃烧室中,由于气流温度低,燃油蒸发性能差,混气在稳定器截面仍是两相的。气流绕稳定器运动过程中,小油珠随气流运动。大油珠由于惯性大,撞落在稳定器表面,形成油膜。油膜沿壁面向稳定器后缘运动过程中吸热、升温和蒸发。蒸发的燃料随气流向下游运动和扩散。This paper summarizes the study of combustion for two phase mixture in afterburner conducted in the combustion Lab. of Nanjing Aeronautical institute in recent years, including experimental investigation on the fuel droplet capture, fuel film vaporization on the surface of flame-holder, experimental investigation on the atomizing characteristics of fuel film at the trailing edge of flameholder and experimental investigation on the flame stability in two phase mixture etc.
