摘要
运用NUMECA的三维粘性流动数值计算软件FINE/TURBO对压气机级和涡轮级的流场进行研究;运用FLUENT软件对两叶轮背部间隙流场进行计算.对数值计算出的压气机和涡轮叶轮的表面及背面压力分布进行积分,最终得到轴向力.
A 3D viscous flow program FINE/TURBO was used to solve the complex flow field of turbine stage and compressor stage. The leakage gas flow field between the bearing box and the impellers is solved by the software FLUENT. The axial thrust can be deduced from the integration of the pressure field and area around both impellers.
