摘　　要：基于定常假设,运用Fluent软件,利用混合平面模型传递级间参数,对静叶不同安装角下的烟气涡轮多叶片通道流场进行了数值计算,得到了温度、压力、出口速度和马赫数等参数的变化规律,绘制了静叶不同安装角下各种参数的体积加权平均XY图。Based on the steady flow assumption, the Fluent software and the transmission-stage pa- rameters of the hybrid planar model are used to conduct the numerical calculation of the multi-blade channel of the gas turbine flow field at different static blade angels. According to the variational rules obtained about temperature, pressure, outlet speed, Mach Number, the volume-weighted average X- Y figure of various parameters under different static blade angles is offered.
