A REVIEW OF RECENT MHD GENERATOR WORK AT THE AVCO-EVERETT RESEARCH LABORATORY
AVCO EVERETT RESEARCH LAB INC EVERETT MA
Pagination or Media Count:
Conceptual plant design, electrical properties of gases, generator fluid mechanics and performance, field coil designs, and long duration testing are reviewed. In the area of gas properties, the experimentally determined conductivity of seeded combustion products is in good agreement with predicted values in the temperature range between 2300 to 3000 K. The study of generator fluid mechanics continued using the Mark II combustion generator. Successful operation at Hall coefficients up to two was achieved. Actual performance of the Mark II generator is discussed. The discovery of high field strength superconducting alloys has important implications for MHD power generation, as well as for many other MHD devices. There is a brief description of these coils as applied to MHD generators, together with an assessment of the economic possibilities they present for use in a power plant.
