Abstract

In this paper, the cascade flow structures influenced by the position of the obstacle inserted in the downstream flow are presented. The experiments were conducted in a stationary cascade wind tunnel, and the results can not be attributed directly to the real rotor channel flow. Nevertheless, they show qualitatively the very complicated flow pattern in the region of the rotor-stator interaction. They explain the existence of very strong variation of the blade loading and high losses of cascade flow due to the rotor-stator interaction noted by previous authors.
