基于静叶不同安装角的增压锅炉烟气涡轮多叶片通道数值模拟

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 .
