Experimental Investigation of a High Pressure,High Voltage Electro-Gas Dynamic Generator.

摘要

The Mixture Condensation Process is compared with the Expansion Condensation Process and experimental data shows the former process produced 2.75 times the power density of the latter process at the same gas density. Experimental results were obtained and equations were derived for point emitters relating current and voltage with the number of point emitters; and the minimum emitter point density with gas velocity and conversion length. The minimum point density is independent of gas density and power density. In a new design conversion efficiency is improved with (1) an emitter of increased point density interspersed with steam orifices, resulting in a smaller exciter voltage and a better mixture of the ions with the steam for production of the charged aerosol; (2) a collector with an increased point density, resulting in a smaller voltage drop to discharge the charged aerosol.
