Title: DIFFUSER, DISCHARGE FLOW PATH, AND CENTRIFUGAL TURBO MACHINE
Abstract:
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.
