摘　　要：为了解某火箭弹控制系统燃气源开槽导管内的气流流动特性，通过ＳＩＭＰＬＥ方法对其复杂流场进行了数值模拟。采用隐式时间分裂格式、幂函数方案及交错网格修正压力等方法，获得了燃烧室后部和导管内气流的速度、压力、密度和温度的三维分布。To find out the flowfield characteristics in the slotted tube of the hot gas generator (HGG) used for a missile control system, a numerical analysis method of this complex flowfields were studied. The computation was based on the SIMPLE method. An implicit time splitting format, an exponent function program and an interlace grid techniqe for pressure correction was used. The three dimensional distributions of the velocity, pressure, density and temperature in the flowfields both at the bottom of the combustion chamber and in the slotted tube were given out.The computational results are in agreement with those from experiments.
