The results are compared with the flow field of the rotating impeller passage of the same fan without inlet box. The differences of the flow characteristics of the rotating passage at the different peripheral locations are revealed. The effects of the complex flow in the inlet box on the internal flow of the rotating impell passage are investigated.展开更多
