This paper is a report on the development of an experimental MHD electrical generator which derives its energy from the combustion of a liquid fuel and oxygen. The fuel burned is a number 2 distillate oil in which a soluble potassium octoate is mixed to increase the degree of thermal ionization in the product gas. The actual generating volume is approximately 125 cubic inches and the rating of 10 KW has been exceeded. The paper describes some of the broad construction features of the generator and problems arising during its operation. Other sections deal with the fuel and combustion systems, fuel characteristics, and the electrical and magnetic aspects. The theory of MHD power generation in a uniform duct is presented. Results of the experiments are presented and actual performance compared with theory. The paper is illustrated with photographs and sketches of the various components and curves of power and voltage.
