Research on transient load for transonic compressor based on dynamic boundaries

  • 摘要: 针对航空涡轮发动机压气机部件的过渡态,基于动态边界并结合双向流固耦合(FSI)方法模拟了跨声速压气机NASA Rotor 67的过渡态过程,获得了考虑叶片弹性变形的压气机过渡过程特性曲线,研究了叶片气动弹性变形对跨声速压气机加速过程中气动参数、流场激波结构演变过程的影响,分析了加速过程中非定常气动载荷与离心载荷共同作用下的叶片变形特征。结果表明:随转速升高,叶片变形对上半叶高区域的总压比和总温比的影响较显著;加速过程中,叶片变形对通道内激波结构特征及其演变有一定的影响;叶片变形主要集中在上半叶高,以弯曲变形为主导,主要由离心载荷造成,加速过程中叶尖区域的叶型出现反扭现象,从而引起压气机气动性能参数的变化。
