Abstract
A boundary-layer turbomachine coupled to a shaft for transmitting power, comprising a plurality of ducts, and a plurality of blades and/or one or more protrusions. The plurality of ducts are defined by duct walls configured to rotate about the longitudinal axis and are concentrically arranged thereabout to convey fluid between inlet and outlet ends. Flow inlets draw the fluid into the plurality of ducts at least partially azimuthally around the longitudinal axis towards the outlet end. The plurality of blades and/or one or more protrusions extend radially in the duct between opposing duct walls. The one or more protrusions may spirally extend at least partially along and around the longitudinal axis to induct fluid into the duct. Slots may be provided in duct walls for centrifugal separation of liquid phase. Systems and methods of generating power using a plurality of boundary-layer turbines, including without condensers, pumps, and/or compressors.
