Abstract:
An experimental investigation has been made to study the effect of casing wall boundary layers upon the rotating stall characteristics of an axial flow compressor in an isolated rotor row configuration. The boundary layer was modified by fixing circular rings of different wire diameters to the outer casing. A significant alteration of the rotating stall characteristics was obtained with regard to changes in flow coefficient at stall onset and cessation. *Replaces A.R.C.33 898
