Study on Electrofluid Dynamic Power Generation.

Abstract

A three-year program to develop and advance Electrofluid Dynamic (EFD) Power Generation technology is described. A range of axisymetric EFD channel sizes from 1/12 inch operating with inlet pressures of 700 psig to the 1/48 inch channel designed to operate with 3000 psig were experimentally studied. Failure of gas-breakdown scaling laws prevented the designed 70 watts from being achieved with the small sizes at high pressure. Experimental work on the high voltage breakdown of high pressure gases including air, Hydrogen, SF6, Argon, Nitrogen CO2, and mixtures using various Freons shows a degradation of anticipated strength at about 10 to the 8th power V/M. Theoretical analyses and experimental measurements have been made on the droplet size and density in EFD generators using humid air for EFD channel sizes from 1/4 inch to 1/48 inch. Analyses also include nucleation and growth of Mercury and steam. A preliminary design study of the short duration airborne 6 MW conversion system and a long duration 1 KW and 100 KW ground based system using EFD is included. (Author)
