| 摘 要： | 以某型发动机为对象,采用CFD数值模拟,研究了高压压气机12级孤立转子在不同叶尖间隙值下的单通道流动细节,分析和比较了不同叶尖间隙值下该级转子的压比和效率,获得了最佳性能前提的叶尖间隙值,并讨论了最佳间隙下的流场结构.结合ANSYS有限元软件评估了转子叶片和轮盘在热-结构耦合作用下的径向应变.研究结果对改进转子叶尖间隙装配和控制具有较好的参考价值.

| Abstract: | Using CFD numerical simulation method,the single-passage flowfield of high pressure compressor rotor-12 with different tip clearances were investigated,and the corresponding total pressure ratio and efficiency were analyzed and compared,then a tip clearance value of optimal performance was obtained.The flowfield structure under optimal performance was discussed next.Finally,based on the finite element analysis software——ANSYS,the radial strain of rotor blade and disc,which are under coupled effect of thermal-structure,were estimated.The research results provide good reference for rotor blade tip clearance assembling and control. |
