Abstract : An experimental investigation is reported of the trajectories and velocities of solid particles suspended in a fluid passing through an axial flow compressor stage. Such investigation is of importance to the study of erosion damage sustained by the blade. Two test facilities were used for this study: a subsonic cascade wind tunnel for compressible flow and a water table for incompressible flow. From the test technique it would appear that the present existing theoretical analysis for particle trajectories through a compressor stage is questionable. The wind tunnel test simulation is preferred for predicting particle trajectories. (Author)
