【摘要】 针对跨声速轴流压气机转子叶排中的流动, 利用高分辨率的三阶NND格式和LU SGS隐式推进迭代法, 建立了孤立转子内三维N S方程的高分辨率和高效率的数值分析程序。用该程序分别计算了NASA 37跨声速转子, 计算结果表明: 所建立的孤立转子程序能够较好的模拟轴流压气机叶排内流动情况。数值分析结果与实验吻合较好, 从而证明了该程序的有效性。更多还原

【Abstract】 Aiming at the flow of isolation rotor internal flowfield in axial flow compressor, this paper adopts third-order NND scheme and the LU-SGS implicit time-marching method. NASA-37 transonic rotors are calculated by using this code. Results of calculation indicate that this code can admirably simulate rotor rows flow in axial compressors. Numerical analysis agrees well with experimental results. Consequently numerical analysis program is effective.更多还原
