Abstract: An assembly is provided for rotational equipment. This assembly includes a first rotatable body and an injector. The first rotatable body extends axially along and circumferentially about a rotational axis. The first rotatable body includes a first scoop with a first scoop aperture that extends obliquely through the first rotatable body. The injector includes a first nozzle orifice and a second nozzle orifice. The injector is configured to direct a first fluid jet from the first nozzle orifice into an inlet of the first scoop aperture. The injector is further configured to direct a second fluid jet from the second nozzle orifice into the inlet of the first scoop aperture.

Abstract: A seal land includes a seal land body that extends circumferentially about an axis and radially between an inner seal land side and an outer seal land side. The seal land body is configured with a plurality of fluid passages arranged about the axis. A first of the fluid passages includes an inner passage segment and an outer passage segment fluidly coupled with the inner passage segment. The inner passage segment extends along a first trajectory within the seal land body towards the outer passage segment. The outer passage segment extends along a second trajectory within the seal land body away from the inner passage segment and towards the outer seal land side. The second trajectory is different than the first trajectory and includes a radial component and a circumferential component.
