(EN) SWIRL BREAKER ASSEMBLY AND ROTATING MACHINE
(FR) ENSEMBLE BRISE-TOURBILLON ET MACHINE TOURNANTE
(JA) スワールブレーカ組立体及び回転機械
Abstract
(EN)
A swirl breaker assembly according to one embodiment comprises: an annular body that extends along the circumferential direction; a flow guide that projects from the annular body in the axial direction, so as to extend along the circumferential direction; and a plurality of swirl breakers that are provided, with intervals therebetween in the circumferential direction, to the annular body at positions which are offset in the radial direction with respect to the flow guide.
