摘　　要：本文将作者发展的定常Ｎ－Ｓ解程序，改编成时间精确Ｅｕｌｅｒ解程序，用于研究转／静干扰问题。对一台高负荷风扇级无粘流场进行时间精确模拟的结果表明，该方法可被应用于轴流叶轮机内非定常流动机理研究。Based on steady Euler solver developed by the author,a new time accurate Euler solver is modified to study Rotor/Stator interaction problems.The inviscid flow field of a highly loaded transonic fan stage is simulated by this time accurate method.The results indicate that rotor inlet flow fields are not affected by the downstream stator at choke condition,but the shock in the rotor will oscillate periodically.Moreover the stator will operate at highly varying incident angle.The method can be easily extended to viscous unsteady flow research in axial turbomachines.
