A fixed vane positive displacement rotary device is disclosed that includes a primary rotor and one or more scavenging rotors rotatably disposed in a rotor encasement. The primary rotor includes a plurality of protrusions. And each of the scavenging rotors includes a first curved surface that is configured to move adjacent to the primary rotor between the protrusions as the primary rotor and scavenging rotors rotate, a protrusion-receiving groove extending that is configured to receive one of the plurality of protrusions therein so that at least a tip of that protrusion moves adjacent to the protrusion-receiving groove as the primary rotor and scavenging rotors rotate, and a second curved surface and a third curved surface extending away from a center of the protrusion-receiving groove on opposing sides of the protrusion-receiving groove that are configured to move adjacent to a leading side and a trailing side of the one protrusion, respectively.
