Research on New Concepts in Energy Conversion.

Abstract

This report is intended to review progress in a continuing study of advanced concepts in energy conversion. Studied is the feasibility of Rankine-cycle space power systems incorporating nonequilibrium MHD generators. The characteristics of such a generator are now reasonably well understood so that the reasons for its less than adequate performance are fairly clear. Three seem most important. The generator tends to be shorted in the flow direction by highly conducting layers on the electrode walls. The effective conductivity and Hall parameter are reduced by electrothermal waves in the bulk flow. Finally, the inlet relaxation is two-dimensional, and occurs much more slowly than simple one-dimensional theories predict.
