Comparison among three models for compressor internal flow

摘要

摘要: 为了更好地对压气机流动进行模拟，在课题组自行开发的结构化有限体积解算器上实现了用于压气机流场计算的混合平面法、谐波平衡法及相滞后法.以NASA Stage 35为例，对3种方法的计算结果进行了比较分析.结果表明：相滞后法的计算精度最高，混合平面法的计算精度最低；相滞后法与半环的双时间推进法结果相近，计算速度提高了20倍；相比混合平面法，谐波平衡法能准确地模拟动静叶间的非定常干涉及进出口参数变化；在谐波阶数达到5阶后，谐波平衡法计算得到的结果不随阶数变化，且与相滞后法的结果基本吻合；混合平面法的计算效率远高于另外两种方法，相滞后法与谐波平衡法在谐波阶数为5阶时的计算效率相当.

Abstract: In order to simulate the flow of compressor better, mixing plane method, harmonic balance method and phase lag method for CFD of compressor internal flow were implemented into an inhouse finite volume code. Taking NASA Stage 35 compressor model as an example, results of three methods were compared with each other. Result indicates that, phase lag method ranks highest in terms of accuracy and mixing plane method ranks lowest; the result of phase lag method is as accurate as the result of half annulus simulation of the flow with the dual time stepping method, and a factor of 20 speedup could be achieved; compared with mixing plane method, harmonic balance method can simulate unsteady interference between rotor and stator and global parameters variation in inlet and outlet accurately; when the harmonic order is set more than or equal to 5, the result of harmonic method does not vary with the harmonic order and matches well with the result of phase lag method; computational efficiency of mixing plane is much higher than the other two methods, computational efficiency of phase lag method is nearly equal to harmonic balance method with a harmonic order of 5.
