A study has been carried out experimentally as well as theoretically in order to understand the mechanism of stall margin improvement of casing treatment. A low-speed compressor equipped with a single rotor was used for the detailed measurement of the circumferentially-averaged-internal flow with and without casing treatment. Based on the experiment, the effect of casing treatment on total-pressure-loss characteristics of the blade row was discussed, and the result was incorporated into the theoretical analysis. Two-dimensional theory of the rotating stall, to predict the onset condition, was applied to each radial section in a stripwise method, and it was found that the agreement between the experiment and the theory was very good for all configurations, with and without casing treatment.
