Abstract:

The paper deals with the results of research on the electrical characteristics of an MHD generator, carried out in a model power plant using the U-02 MHD generator. In this device was tested different types of MHD ducts which vary both in design and in the structural materials used for the electrodes and the insulating walls. As a result of this work the power of the generator was raised to 42 kW and the operating time was taken to 100 hours. The maximum power extracted from a single pair of electrodes has reached 2.5 kW and the current density at the electrodes is 2.5 Asq cm in the short-circuiting regime. A great deal of experimental data was accumulated during the development and testing of the duct designs, and the paper is devoted to an analysis of this information. The object of study is a Faraday-type MHD generator with segmented electrodes, operating in a subsonic gas-dynamic regime. Author
