摘　　要：以装有三级斜切式径向旋流器的中心分级燃烧室为研究对象,利用数值模拟和控制变量的方法分别进行了值班级第一级旋流器斜切孔角度、值班级第二级旋流器叶片安装角和主燃级旋流器旋流孔角度对中心分级燃烧室热态流场影响的仿真和对比分析。结果表明:当值班级第一级旋流器斜切孔和值班级第二级旋流器叶片安装角角度分别为25°和30°~45°,主燃级旋流器旋流孔角度为45°~60°时,中心回流区的形状最好,中心分级燃烧室热态流场的品质最佳。Taking the central staged combustion chamber equipped with a three-stage oblique tangential radial hydrocyclone as the research object,the effects of the angle of the oblique tangential hole of the first stage hydrocyclone,the installation angle of the second stage hydrocyclone blade and the angle of the swirl hole of the main combustion stage hydrocyclone on the hot flow field of the central staged combustion chamber are simulated and compared by using the method of numerical simulation and control variables.The results show that the shape of the central recirculation zone is the best,and the quality of the hot flow field in the central staged combustion chamber is the best when the installation angle of the first stage swirl hole and the second stage swirl blade is 25°and 30°~45°respectively,and the swirl hole angle of the main combustion stage swirl is 45°~60°.
