Abstract:

The character and distribution of flow in the channels of a large-scale model of a centrifugal compressor impeller are explored and measured. In order to make a more detailed study of the flow that has been discovered, a new series of tests has been carried out. The complete rotor was replaced by simplified models of single channels, in which the flow could be compared while the channel was stationary, or rotating. These two-dimensional channels were given a range of divergence angles, and the flow was compared with that in stationary diffusers. Channel-exit speed and stability profiles are presented covering ranges of channel divergence angles, and Reynolds and Rotation Numbers. Smoke visualization pictures enable the flow within and downstream of the channel to be seen, and show the location of the flow detachment point on the suction wall. Author
