Abstract: front page image
(EN)This diffuser (8) for a centrifugal turbo machine (E) comprises a radial flow path (3) and a bent flow path (4) which connects the radial flow path (3) and a discharge flow path (6) which circumferentially conducts a flow. If the inner peripheral-side radius of the bent flow path (4) is designated as (R), and if the axial flow path width of the radial flow path (3) is designated as (h), then the relationship of 0.2 ≤ R/h ≤ 0.5 is satisfied.
(FR)L'invention concerne un diffuseur (8) destiné à une turbomachine centrifuge (E) comprenant un trajet d'écoulement radial (3) et un trajet d'écoulement courbé (4) qui relie le trajet d'écoulement radial (3) et un trajet d'écoulement d'évacuation (6) qui conduit un écoulement de manière circonférentielle. Si le rayon côté périphérique interne du trajet d'écoulement courbé (4) est désigné par (R), et si la largeur de trajet d'écoulement axial du trajet d'écoulement radial (3) est désignée par (h), alors la relation 0,2 ≤ R/h ≤ 0,5 est satisfaite.
(JA)本発明の遠心ターボ機械(E)のディフューザ(8)は、半径方向流路(3)と、半径方向流路(3)と周方向に流れを導く吐出流路(6)を繋ぐ曲がり流路(4)とで、構成され、曲がり流路(4)の内周側半径を(R)とし、半径方向流路(3)の軸方向流路幅を(h)とした場合、 0.2≦R/h≦0.5 の関係がある。
