The description of a combined thermodynamic power system using a two-phase fluid and air as working fluids

摘要

A combined thermodynamic power system is described that uses a two-phase fluid (air and water) to form the basis of a cycle that employs the isothermal compression of the working fluid to improve the overall efficiency. The compressor and the expander described in the system utilize sliding-blade rotary devices that together make up an air-heat engine that operates on a modified Brayton cycle. Key to this device is the utilization of an isothermal compression of the air and the efficient use of waste heat in a regenerative process to achieve high thermal efficiency and reduce environmentally damaging emissions. In addition, a special pre-chamber/vortex combustion chamber allows for the introduction of heat in an environmentally friendly manner.
