Open-rotor engine noise analysis based on Mohring acoustic analogy

  • 摘要: 为了系统地研究非均匀流场中开式转子的噪声特性,运用计算流体动力学(CFD)和计算气动声学(CAA)无限元法相结合的方法,对开式转子的频域噪声做了数值预测。通过采用基于可压缩修正的Spalart-Allmaras湍流模型对非均匀流场中开式转子气动特性进行分析,运用声学无限元方法,引入平均流场并将其插值到声学网格作为背景流场,对转子噪声和噪声传播进行数值模拟,并对特征点做频域分析。由噪声分布云图和远场特征点频谱曲线分析得出:非均匀流场中开式转子发动机的峰值辐射噪声主要集中于低频范围,噪声最大值为142dB,峰值噪声频率为115Hz,随着频率增加,交替出现多个局部峰值声压,噪声衰减速度减小。为下一代开式转子发动机噪声预测提供一种方法。
