摘要
为研究先进驻涡燃烧室的燃烧特性,采用三维数值模拟方法,得出AVC中钝体布置对旋涡稳定性和总压损失系数的影响规律,并恰当选择AVC几何结构.对AVC燃烧和污染物排放特性的研究结果表明,AVC具有燃烧稳定性好、燃烧效率高、污染物排放水平低等优点.
The three-dimensional numerical simulation was carried out to study the combustion characteristics of advanced vortex combustor （AVC）. The effect rule of distance between forebody and after-body and width of after-body on flow resistance, trapped vortex configuration and stability was obtained , and geometry structures of AVC were determined. Simulation on the AVC combustion characteristics and pollutant emission characteristics shows that AVC has advantages of stable combustion, high efficiency and low pollutant emission.
