Abstract
A blade assembly for a turbomachine compressor includes a plurality of individual devices acting on the flow. The individual devices are provided upstream of the blade assembly and are formed at least so as to generate vortices. Each of the individual devices is arranged on an upstream face of a shroud around which a recirculating flow passes, circulating in a cavity. The recirculating flow is reinjected into the principal flow such that the individual devices act simultaneously on the principal flow and on the recirculating flow.
