摘要
应用多重网格技术,对轴流压气机跨音风扇转子叶片内部流场进行了数值模拟。利用网格自适应技术研究了计算网格和湍流模型对实际轴流压气机内部复杂流动计算结果的影响。对跨音风扇内部流场特性进行了详细分析,给出了粗细网格下风扇性能曲线并与试验值进行了对比。
A Multi-grid Technology is applied to numerically simulate the inner flow field of rotor blade of axial compressor transonic fan.The Grid Adaptive Technology is used to the calculation and the effect of turbulence modal on the actual inner flow field complicated calculating results of axial compressor is presented.The inner flow field characteristics of transonic fan are analyzed in detail.The performance curves under the condition of coarse and fine grid are given and compared with testing values.
