Abstract

A fluid flow machine comprising a first rotor (110) and a stator (130) positioned alongside the first rotor, each of the first rotor (110) and the stator (130) comprising a plurality of circumferentially distributed turbomachine blades (111, 131), wherein the stator comprises a stator shroud structure (132) comprising a stator shroud surface (133) and the first rotor comprises a first rotor shroud structure (112) comprising a first rotor shroud surface (113), the stator shroud surface and first rotor shroud surface together at least partially defining a radially inner flow surface of the fluid flow machine, wherein the first rotor shroud structure defines a first cavity (114), the first cavity being disposed radially inward of the first rotor shroud surface, and wherein the stator shroud structure comprises a first protrusion (135a), the first protrusion being disposed radially inward of the radially inner flow surface, wherein the first protrusion extends in a direction with an axial component and into the first cavity of the first rotor shroud structure.
