Abstract: A modified two-phase refrigeration cycle compresses a working fluid, condenses the working fluid into a saturated or supercooled liquid, expands the saturated or supercooled liquid into a two-phase fluid, and evaporates the two-phase working fluid. The modified two-phase refrigeration cycle reduces irreversibilities imposed by conventional refrigeration cycles and extracts energy from the working fluid during the expansion process. For instance, a system that employs the modified two-phase refrigeration cycle includes a two-phase expander to reduce irreversibilities during an expansion process and extract energy. In some instances, the system includes a two-phase compressor to compress two-phase fluids for varying loads and environmental conditions of the system.

Abstract: Prime movers are provided that can include: a fixed member in operational relationship to a rotating member; a reciprocating vane assembly operationally engaged with the rotating member; and a track member about the rotating member and engaging the reciprocating vane assembly. Engines are provided that can include: a stator in operational relationship to a rotor; a reciprocating vane assembly operationally engaged with the rotor; and a track member about the rotor and engaging the reciprocating vane assembly. Processes for powering a prime mover are also provided, the processes can include engaging vanes between a fixed member and rotating member to create compression and expansion zones, the engaging comprising guiding the vanes from a track member about the rotating member.
