Electrogasdynamic (EGD) power generator employs an electrically charged working fluid. When the electric charge is moved by the working fluid against an electrical force, the kinetic energy of the working fluid is converted to electricity. An EGD generator may be integrated into an ejector to form a combined heating, cooling and power generation system. The system may be driven by solar energy or waste heat. The experimental setup of an EGD ejector system is described in this paper and some experimental nesults are presented. The EGD output power is very limited for air, R134a, R123, and HFE7100 as the working fluid. The change in the nozzle outside size due to integrating an EGD generator has little effect on ejector performance.
