Abstract : Computer Studies of electric fields for an electrofluid dynamic generator of realistic geometry are presented. A technique of numerical superposition is described and applied to the specific generator configuration. A study of electric breakdown in the absence of charges is presented. It is concluded that a more sophisticated treatment of the breakdown phenomena will be required to accurately predict breakdown in inhomogeneous electric fields and a possible technique is suggested that would be compatible with the available computer program. In addition, electric field studies are presented on basic configurations of simple geometry that are not amenable to analytical solutions of Poissons equation. Finally, a discussion is presented of a detailed model of the fluid flow field in the generator which is required to determine more realistic charge densities and gas densities in an electrofluid dynamic generator.
