Abstract
An experimental investigations have been carried out in the influence of structural parameters of recess vaned casing treatment on the efficiency and the stall margin of an axial flow rotor. Tests were conducted under the condition of different axial positions, number of vanes and different length of the casing treatment to define the optimum position. In each case, the characteristics with casing treatment were compared to that with solidwall. The increases of operating efficiency in the flow without drops were observed. The results can be used as a guide for the selection of configurations in the casing treatment design.
