Book Description
The successful design of full-scale open-cycle, coal-fired MHD generators for baseload electrical production requires a detailed understanding of the plasma chemical and plasma dynamic characteristics of anticipated combustor and channel fluids. The report documents the development of a diffusion controlled heterogeneous condensation model and channel heat loss model for incorporation into the PACKAGE code used to calculate core flow plasma properties and generator efficiency. PACKAGE calculations comparing realistic baseload subsonic and supersonic generator models are also presented. Progress on the refinement of a laboratory scale coal combustion plasma source and its associated molecular beam mass spectrometer diagnostic and diode laser absorption plasma temperature measurement systems is documented. Finally, progress on the development of a numerical model describing arc behavior in MHD electrode boundary layers is presented.
