Experimental study of flow distribution characteristics for a rotor-stator system

The flow characteristics of rotor-stator cavity system with blade-cooling flow and disk-cooling flow was experimentally studied. And, the cooling flow rate of the clearance between stator and rotor as well as the hole of rotor flange was obtained. The experimental results show that: The blade-cooling flow rate will increase with the total flow rate and rotating speed; the ratio of the blade-cooling flow rate to the total flow rate will increase with decline of the total flow rate, and increases with the rotating speed. The blade air flow is almost half of original flow when the numbers of holes become half of original holes.
