| 摘 要： | 通过对尾迹-叶片干涉和激波-叶片干涉这两类典型转静干涉流动的模拟,对3种基于傅里叶分析的时域非定常计算建模方法,即形修正相延迟法、空间-时间梯度法和谐波平衡法进行对比分析；详细考察它们的区别与联系,不同方法的计算准确度和计算速度.计算表明:3种建模方法都可以很好地捕捉到非定常流动细节；与传统的时间推进法相比,计算速度提高了几倍到几十倍,可用于工程设计之中.

| Abstract: | Comparative study on three Fourier-based time-domain unsteady computation methods, including the shape-correction phase shift method, space-time gradient method and harmonic balance method, was carried out by simulation of two typical kinds of rotor-stator interactions, i.e.:wake-blade interactions and shock-blade interactions. Differences and relations between these computation methods were investigated in detail, and their computational accuracy and speed were also analyzed. The results indicate that three methods can resolve the unsteady flow details well. Compared with the conventional time-marching method, the computational speed of these methods can be enhanced from several to dozens of times, making these methods applicable to daily design process. |
