Abstract

The invention relates to a rotor element (10) for a fluid to flow around and for a rotor (20). Said rotor element comprises a rotor blade (12) having two lateral surfaces and a flow conduction surface (14) associated with the rotor blade (12), the wake of said flow conduction surface influencing the flow impacting one of the lateral surfaces of the rotor blade (12) at least to some extent.
