摘要:
以125 MW轴流式汽轮机某一冲动级叶片为研究对象,利用商业软件ANSYS CFX对该级静动叶片的气动性能进行了三维数值模拟优化计算.结果表明,通过优化前缘和尾缘椭圆率、相对节距以及其级间配比等几何参数,降低了表面压力差分布,有效控制了二次流损失;叶片等熵效率提高了0.43％,总压损失系数降低了0.005左右.优化改进后,叶片的气动性能得到提高,降低了其能量损失,增加了汽轮机效率.
Abstract:
The analysis was held with the 125MW axial flow steam turbine impulse stage blade.The three-dimensional numerical simulation and optimization were conducted by using the commercial software ANSYS CFX.The results showed that the pressure distribution of blade surface reduced,and the radial secondary flow loses was controlled effectively,with optimizing the structure geometric parameters such as ellipticity of the leading edge and trailing edge,relative pitch,inter-stage ratio,and so on.Isentropic efficiency increased by 0.43％,the total pressure loss coefficiency decreased about 0.005.After the optimization,the aerodynamic performance of the blade increased,and the energy loss in the blade decreased and the efficiency of steam turbine increased.
